Painting Basics & Techniques – Part 1 of 2 with Kevin Tetz – Eastwood


great techniques gun handling techniques
gun setup air hose handling sequencing a paint job and we’re also going to be
talking about a whole lot of other things like airline systems the
importance of filtration the importance of air volume rather than air pressure so the other cool thing is that below
this you’re going to see icons pop up talking about some of the equipment and
tools that i’m going to be holding up there all available from eastwood and
some of them are on sale you can find all of this stuff at East
was so I just want to let you know that in advance the other cool thing is that you can
actually feel questions you can you can talk to us and at the end of this
presentation we’re going to answer a few of those questions that you guys have a
switch is one of the beautiful things about what we’re doing we are alive it’s like it’s like a news report we’re
live here and it’s very cool to be a part of this if you don’t know who the heck i am i’m
kevin taste I I own and operate and produce the patron location series also
do some TV shows i do the truck show on spike and I just want to say out loud I’m a really good painter now that might
sound almost full of stuff like that but there’s a reason that i can say that I’m
a really good painter is because I’ve painted thousands of cars it’s not because i have God’s gift of
painting you guys anybody can be a really good painter it’s repetition it’s conscious thinking it’s muscle
memory and that’s what it is you gotta pay attention to the rules get your
setup right and do it over and over and over and over and over and over and over
again to practice practice practice practice practice and you guys if you’re
a beginner if you’re a pro you get better it’s
muscle memory so when I say I’m a really good painters because I’ve done it a lot
so all you gotta do to get your skills up is just practice so let’s get started we’re going to talk
over here a little bit about air compressors now the air compressor is the heart of
your shop I’ll say it again air compressor is the harder shop
everything else depends one hundred percent on the quality and
the volume of air that you’re putting out here’s some requirements i hope you’ve
got a notepad if you don’t these presentations are available for download
later you can view them later on and you can take some notes because there’s a
lot of important thing there’s a minimum that you need to paint
a whole cart you need at least a five horsepower compressor a two-stage air
compressor preferably with a cast iron pump a minimum of a 60-gallon tank and
you’re talking about spending some money you have to have the proper amount of
air volume air pressure doesn’t matter in painting any more air pressure is for
your tires it’s a totally different set of
equipment and set of systems air volume CFM is key and when you read the guns
what they are required to have it CFM it’s not pressured about 12 to 13 cm
some of the lower drawing some of these two guns are drawing less but he hears
the difference you can have you see the difference in
the inside diameter of this and this pipe ok you can have the same air pressure or
the same volume air pressure in both of these pipes and the volume that’s coming
out the end of this one is much greater than the volume that’s coming out the
end of this one so the volume is what atomizes and
breaks up the paint so you can breathe through a straw or you can breathe
through a culvert pipe breathing through a culvert pipe is easier and it’s easier
to paint so think of that analogy when you’re setting up your system so
now that you’ve got your air compressor I wanted to show you something else this
is what I’m plumbing my main paint shop with its it’s a
system that i got from eastwood is three-quarter inch inside diameter
airline and the fittings are really cool there are push lock style fitting that
has an o-ring system and a feral that compresses on top and it makes it makes
short work and make sure your airline routing very very easy and the system
that I’ve got has a hundred feet of the Blue Hose it’s got several fittings
several junction several unions and the cool thing is that it’s flexible so you
can bypass a lot of the need for four look what you can do with it and it’s
lightweight aluminum with with a nylon membrane and it’s really versatile so i
highly recommend that that again it also is available these wood let’s talk about filtration you’ve got
to have clean air got to have lots of air but you’ve got to have clean air so this is the little ball filter that
you you can buy and these you can screw onto the end of the paint gun and this
will filter somewhat of the debris is i don’t recommend just this this helps if
you’ve got a problem sometimes this can solve it on the fly don’t depend on this – to save your
paint job this is called a desiccant snake it’s filled with desiccant now we’re
going to explain this again in just a second so hang on this goes in line to your air system and
it’s got a silica inside it that will absorb moisture it doesn’t compress it
doesn’t interfere with your CFM delivery so this is a nice fix if you’re doing a
limited amount of painting and I it this relatively inexpensive when they
wear out you replace them then you get into your different regulators and
filters this is just a regulator with a gauge on
it with no filter whatsoever this has got a filter you can mount a
gauge and mounted in line with the regulator you’ve got to have a regulator
to get your air pressure where you want it this is the mack daddy of all of it this
is a three states a multi-stage desiccant system now desiccant is this stuff these
aren’t silicon under silica what’s silica beads that absorb moisture and it
works exceedingly well these packets or what you get with modern electronics
when you buy a TV when you buy a computer they’re all packed everybody’s seen
these they come flying out of the box you throw in the trash they are the same thing is in this and
they’ll be in your canister in line in your air supply and they will filter out
the moisture this is multi stage these two are
designed to catch particular this is designed to catch moisture and you again you’ve got to have clean air you got to
have lots of air but you’ve got to have cleaner so think about systems like this now i want to make something very very
clear if you buy this stuff and you don’t install it correctly you are
wasting your money so if you’re not going to install it
correctly don’t don’t even bother you just you
know throw caution to the wind here’s what i’m talking about what
happens when air compresses it’s a piston just like an engineered
super heats that air when it comes off the manifold it’s hot so if you put your expensive
relatively desiccant system right on the manifold or a couple of feet off the
manifold that air is still packed with moisture and it goes right over top of
the filters it doesn’t get separated so what you
have to do is sit this at least 20 feet preferably 50 feet away from that hot
manifold of your air compressor and you might be saved yourself i’m in a one big garage i want to
plummet i’m in a small shop I don’t have 50 feet i’ve only got 30 foot walls here’s something now don’t plum with PVC
i want to say that out loud right off the bat this is PVC and i made
this piece just for demonstration purposes so what you can do to cheat distance is
go up and down and up and down now this is 10 inches here this is 20
feet of three-quarter-inch ID piping so if I was to double this I’ve got 40
feet of of drying air of giving my air the the capacity to separate from the
moisture with this and it also gives you the opportunity to mount a ball valve
bridge drain valve down here and get the water
out and be able to evacuate so it doesn’t fill up with water so thank your
way through this stuff you can cheat distance with something like this plump it up and down you don’t have to
have a 50-foot wall so keep that in mind when you’re planning your airline system let’s get to the good stuff let’s start
talking about spray guns before we go into demos on the guns one of the questions that keeps coming
up and and we’ve talked about this with the east with guys before we planned
this this presentation is gun settings air pressure settings yes you have to
have up you have to have the pressure set right
and the gun recommends 10 pounds of the air cap it almost makes me angry that the gun
manufacturers say 10 pounds of the air cap because for you and I there’s no way
to verify that it’s 10 pounds at the cap is not a gauge on the gun and there’s
not a gauge of fits on the inlet to gauge the air pressure at the cap what you have to do is factor in the air
inlet pressure right here now ten pounds at the cap a rule of thumb is that is
going to give you between 30 and 34 pounds at the inlet so when they say ten pounds at the air
cap just don’t even worry about that worried about the inlet air pressure
which is the pressure coming in to the base of your gun now here’s the thing to people say well
I set my air pressure but when I pulled the trigger is it goes all screwy well
when you set your air pressure make sure your triggers fully depressed
and whether you got a wall regulator or a regulator on your gun pull your trigger let air going through
it is pressure is set with the device completely open so keep that in mind as
well now what am i doing with these things
taped to my paint guns extended stupid but there’s a method to the madness here these are what I call dry training
guides and they’re perfect for for learning gun handling techniques like I
said right off the head it’s muscle memory its repetition and these give you
the opportunity to to understand what it feels like to be in the awkward strange
positions without even having a single bit of fluid go through your paint gun let me show you what I’m talking about
now the bristles the bristles of this brush represent where I want my spray
gun on the surface and this right here this is a Ferrari just in case you were wondering now what I’m doing is I’m
practicing my technique by keeping the bristles just barely touching the
surface and I can practice my overlap and I can practice moving i can do a
rehearsal on the panel to see if I’m gonna run over it but the most important
thing is that up here in my wrist I’m getting a feel for how it feels when
i’m in in the right position in a nice comfort zone using correct technique my wrist is well i’m going to overhear
my wrist is broken it’s not like that i’m not sweeping I’m
going in a linear format and my wrist break so that the brush on the end of
the spray gun is a beautiful training tool and it’s surprising how effective
it is for you to it really sets the light bulb off to know exactly where
your surfaces in relationship to your spray gun takes a lot of the pressure
off another great idea is this guy right here the reason is sometimes it’s easy to get
lazy with our spray technique now when i’m lazy my spray pattern is
like this when I’m just kind of pointing at the panel with the gun and my pattern
obviously is going to get really heavy down at the bottom and really light at
the top and it’s going to tiger stripe it’s going to be inconsistent it’s not
going to be what I want and this gives me the ability to test myself and keep
my gun perpendicular to the surface 90 degrees spray pattern parallel to the
surface so again it’s a dry training guide that
shows me if I’m off-kilter one way or the other and lets me memorize this
natural position that i’m going to have the best painting results so keep that in mind when you’re
spraying paint rehearse Ron covell talks about being excuse me
when he’s welding he does rehearsal to get is his comfort zone to get his is
muscle memory built up before he starts painting and before he starts welding
and painting is absolutely no different you want to be in a comfort zone what
I’m talking about the comfort zone is I don’t want to be out here going crazy painting out here and and I don’t want
to go over here like this I want to have his own to where I’m in control painting is all about control your
controlling your air your gun your fluid and your surface so if I’m out here if I’m out of control I take a step get in the comfort zone so
keep that in mind as well now i’m following an outline because we want to
make sure you have time for your questions so I’m gonna be looking at
this from time to time ok so we’ve talked about spray gun
technique let’s talk about air hose technique and
why is that important I’ll show you another thing to consider as well as
your CFM on your air compressor is CFM in your air hose I don’t recommend anything longer than a
25-foot air hose because you you you experience pressure drop over distance the other thing that’s very very
important is to keep a 38 inside diameter airline and three eighths ID
fittings which these are not these are five sixteenths they’re not three
eighths the difference between this and the professional spray gun setup that
I’ve got in my booth is night and day I have seen an itch difference in this in
the length of the spray pattern by going to three eighths ID fittings very very
important for a good effect of a good effect of spray delivery so what I’m talking about with the air
hose this is nobody’s going to do this really
unless you forget when I’m over here guess what my air hose is do it it’s
touching the panel and at the very least i’m not going to bunch of trash into
what I’m about to paint or worst case scenario i’m dragging my air hose into
wet paint not good so this is what i recommend
take your air hose clip it over the shoulder that’s not good enough because look what
happens it can call off the shoulder guide it with your other hand and you’re
using kind of a push poll you’re controlling your environment there goes my guys and
as I’m you see what I’m doing as i’m increasing my distance away from my body I’m feeding the air host when I come
back I’m pulling it back take a little while to get that memorized but it’s
very important to do so just think your way through this stuff in a rocket
science but it takes some thought and it takes some repetition we’re going to put this over here let’s talk about gun setup now that we
know what we’re gonna paint we know what we’re gonna paint with and
by the way this is this is the the concourse gone from us what is a very
nice piece of gear of the evolution guns or what you just saw they’re very cost effective and they’re
nice guns i use these guns on jaded when I shot it and I’m very happy with the
results sometimes even the best spray guns can
get a goofy pattern just due to maintenance and stuff collecting into
the air horns and things like that so right here this is a representation this
is an elliptical pattern this is what you want to see this is
like a football shape and that’s what you want to see out of your spray gun now if it’s like this if it’s heavy on
each side and light in the middle that means you’re blowing it out with
air pressure your cranked up too high some of the spray guns only want 20
pounds at the inlet 20 to 30 pounds is typical so you have the opportunity to test on
some sort of a take-off part or a piece of cardboard like this set your spray gun before you paint your
car just like you’re welding well on a piece of scrap before you you
put your quarter panel in so this one right here this means it’s
heavy on one side having on the other side but it’s it’s cyclical it’s it’s
it’s a curved like that typically what that means is that one of
the air horns is blocked these are the air horns on the spray gun
tip now one of those might be crusted up and blocked so you know it’s a simple
matter of cleaning it but that’s what that will tell you so see now check this out – this is the
digital air pressure gauge this thing’s Nate if you got to have a
pressure gauge on the end of your gun this allows you to to adjust on the fly
and it’s very accurate so we’re going to stick with a fairly
low pressure we’re about 20 for the inlet so let’s do it let’s give it a shot so
what do we got there we have the perfect elliptical pattern we’ve got the
football right there buddy the reason we have that is because we’re
allowing the spray gun to do what is designed to do I’ve got the fan fully open I’ve got the
fluid delivery fully open that’s not to say you have to shoot like
that all the time but that’s the optimal setup for me now we’ve got an air volume adjustment
down at the bottom of the gun body which is nice to have if you want to adjust on
the fly here if you’re going into some some tight recesses it’s nice to have that and here’s your
fluid delivery here’s your fan that’s a fan that’s blue delivery so
watch what happens when I tweaked and i want to improvise is my pattern starts
going away and what’s going to have to you right there if it’s going to run all over the place
you know we’re not doing a collages or or art work we’re painting cars and we
want a nice overlap so you can if you’ve got a cylinder to get inside it’s really uncommon for me to recommend
that you choked your your fan pattern down and it’s very uncommon for me to
recommend that you choked your fluid delivery down here’s why see what I’m doing there it’s misty what’s going to happen is I’m
going to get a rough surface i want a flat surface i want the pain to flow out
and self level so I want to make sure that i’m letting the expensive spray gun
do it is designed to do now I know some of you guys are saying
this knucklehead is showing me how to spray paint that he doesn’t have any
safety equipment on here I want to show you something this is acrylic craft paint I’m not
being dangerous here there’s no overspray in the air because this is a
high quality HVLP gun it’s not given me over spray and this is
water-based craft paint now when we do make some overspray of
course i’m going to have a mask on so well I want to make sure that you
understand that i’m doing this for demonstration purposes only and that
it’s a safe way to demonstrate these techniques to you guys so always always please keep safety in the forefront of
your mind these chemicals that were using when you comes time to paint are
dangerous and their hazardous to handle as well as to ingest into our body so
please be careful and this is actually a good tip for you
guys as well get some craft paint it’s not that expensive it’s certainly not as
expensive as automotive paint and it allows you to play around with your
equipment and set things up and and get a feel for what you’re doing so let’s talk about let’s talk about overlap what am I talking about with overlapping
that’s a universal spray technique that you want a 50-percent overlap what am I talking about with that I’ve
made a pass there a 50-percent overlap means that i’m moving halfway down fifty
percent from that pass and backtracking so this way fifty percent down overlap
fifty percent down overlap fifty percent down overlap now i’m stopping and starting and you
can see what’s happening as well you don’t want to do that because you
get a heavy build up on the edges I stopped and started so I could talk to
you guys and show you but you don’t stop and start with your fluid delivery when
you’re painting to ease the trigger off because you can keep the air going the
same time you’re delivering you delivering paint so here’s your technique it’s not perfect it’s the first coat is
black on the light substrate so that’s what i’m talking about with overlap
fifty percent overlap you want you want your vehicle to appear as though it’s
been dipped you don’t want random dry spots and a 50-percent overlap or some
kind of an overlap helps you build that code from one point to another point so
very very important to perfect your overlap and pay attention to what you’re
doing and the gun handling techniques will allow you to be in a nice
comfortable position in your comfort zone while you’re doing that speaking of
comfort your hand this is your guy this is what’s what your eyes are telling to move through
your brain so here is your standard prone position for a spray gun if I want
to pay up high like that on a van or something like that if I keep the same hand position it’s
goofy I’m going to get a heavy pattern on one side so here’s something that I’ve learned
over the years you can change your hand position see how my wrist is broken there you can
change your hand position to to suit what you’re trying to spray so I’ve just suggested my hand position
and as I’m coming down I’m unlocking my wrist and now i’m in
the prone position the same thing goes for getting down a
little bit lower now typically I get down on my knees I’m old I’m old as dirt
my knees hurt I don’t want to get down on my knees in a concrete floor anymore that was in my twenties I’m not that
anymore so what I’ve also learned how to do is adjust my spray gun and when I cup
it like this but my palm over top of the controls now guess what I can do I’m down here
and I’ve got a parallel pattern just like that perfect so if i don’t want to get down
like this on my knees and getting my comfort zone I can make a quick adjustment of my hand
and go from the prone position to this position here and have perfect technique
so keep that in mind when you’re moving around on a larger vehicle so we talked
about overlap we’ve talked about getting your gun set
up properly we’ve talked about about proper
techniques handling your air hose here’s something is very important I
want to talk to you guys about sequencing a paint job here’s the analogy you want your car to
appear as though it’s been tipped as though you’ve grabbed the
covers and pull them up from your feet all the way up to your neck in one
continuous coat sorry if that’s goofy that’s just what
it made me think of but you have to sequence your paint job on a complete
overall and this comes up an awful lot in in the website forms that i that i
visit the eastwood online restoration forum where do you stop where do you start let’s talk about how
to sequence a paint job but can do we decide to go over on that
side are you okay there okay now keep in mind
this is my RC mustang it’s clear and i’m going to be drawn all
over it so obviously in this frame with you
can’t move the car around but this this is what I’m talking about now I always start on the roof of the
vehicle in an overall there’s a couple of different reasons for that typically your air flow is coming from
the top down and creating an envelope around the vehicle even in a semi drown
or a crop a cross craft paint booth the top surfaces are going to get hit
first if I shoot the sides and then come up to do the top last I’ve got wet paint
here that i have the potential of messing up so when I start here and then
work my way around the vehicle and come up here by the time I get back to the second
coat on that top well it’s probably drying up for me to stood to start again
and I don’t risk messing up my sides anymore so the sequence that I’ve
learned over the years i call now this is in the Patriot asian video series i
go into great detail in the videos to demonstrate this but i’m going to go
ahead and do it right here basically what I do is I start I like the driver’s
side I want to start on the driver’s side and
I do what’s called a push-pull method I’m going to explain push-pull very
clearly on a Ferrari right here so what I do is step number one I paint
from the edge from the drip rail to the middle now a lot of guys start from the middle
and work your way down I don’t like it I don’t like doing that because you get a
dry spray in the middle and its tax the paint up so push we push to the middle now we
jump over to the other side and we start from the middle where it’s still wet we grab that wet edge and drag it across
that step number two now I’m leapfrogging I’m leapfrog and that’s
what that means you’re going from side to side to side to side to side and
you’re creating a wet surface that grows through the car so step one step two I’m leapfrogging over back to the
driver’s side quarter panel and I paint my quarter typically i like to start from the
bottom and work my way up because that allows me to push across
the side so i’ll come up over here right to the sail panel and then i’ll eat proc
over to the other quarter panel and i paid from the bottom up not riding on my
door gap and i’ll explain that in just a little bit and i paid my other quarter
panel and because I’ve got a wedge here that i was just at now I can paint my
way across that rear deck because I can reach it easily from the back bumper
position now I can catch up with my wedge now that I’ve got this I pick up the
tail panel and I paint the tail panel now I’m leapfrogging back again over to
hear my edge here is still wet enough to where I pick up the door and I sprained
my way up the door getting past my panel gap there’s a
really good reason for that past my panel gap and it makes sense
just to stop and start at the panel gap because it naturally breaks up the car however due to surface tension you’re
going to have a heavy build up on that gap if you’re doing a metallic or a
candy it can really really bite you in the
buns and make sure that you see that transition you don’t want that so I pet
it past my panel gaps and I leapfrog over to the other side hope you’re getting the picture and we
paint our way up this door again again pastor panel gap so now what we’ve got is what’s called
the doghouse it’s the front end of the car this edge is still wet because i was
over there less than a minute ago but it’s dry enough now to pick up the wedge
and I worked my way forward so I pick up the fender work my way
around the wheel and I push my way across the the same way that I did on
the roof and this is the push-pull method you push to the middle and then
you pick up the middle on the other side you walk around pick it up and you pull
it from the wedge and you keep it a continuous overlap all the way down
until you’ve come all the way across the doghouse and this edge here is still wet
enough that you can you can have this continuous coating and if you got a
lower fascia grill pick up your dry edges there and you’ve
got one continuous code on that paint job that looks like it has no dry spots there’s no transitions and
you know where to go and typically by the time you work your
way around a car it takes 30 to 40 minutes to do a single code on a car
well there’s your Flash time so – then you can go into the spray booth make sure got your cup again and start
over start with your second coat or your third coat so that’s how I like to sequence a paint
job and here’s another demonstration go back over this hot rod here and we do
have a little bit of time ok so I’m coming over here if I stop
right here here’s what that gap looks like that’s
looking down at that door now my paint is going to bubble up here it’s going to
be get really happy right there you’ve seen this on cars on original
equipment cars so if you stop and start right here you’re just accentuating that
and you’re building up crazy layers of paint right here right on that gap you
don’t want to do that you want to the first coat maybe its prey up till here when you
come back around for your second code stretch it over to here on your third
coat back it off over here make sure you’re getting three full coats change
the position of that that will really help you especially with translucent
colors or candies that is a that’s a great technique if you’re working a
candy walk beside that’s a that’s an advanced technique but this right here
will keep you from having runs in the gaps nobody likes the runs no different in
painting yeah yeah
