    i didnt learn anything..this man cant explain this good maybe he should demonstr8

  • dufondutrou says:

    you are kidding right? who are you talking to? you said adjustment to the gun…. not basic use!

  • paskom ranger says:

    helpful information for beginner … awesome .

  • Car Addict Garage says:

    I am glad you found it useful. I have some other gun adjusting videos on my channel. Thanks for watching my videos!

  • Christian Carter says:

    Great video, are the gun adjustments different for using non waterborne paints… like celulose based paints?

  • Car Addict Garage says:

    I am not sure about cellulose paint, but for automotive waterborne paint, the adjustments are very similar! Thanks for watching!

  • Car Addict Garage says:

    This will depend on how much spraying you do or if more than one person will be using it at the same time. I would find the manufacture of the compressor you are thinking about buying and give them a call. They will be able to give you a specific answer. Thanks for watching!

  • Car Addict Garage says:

    Let me know how it works or you. You're right, Iwata does use less air pressure than most others. If you are new to spraying, it may be better for you to spray a little further than recommended to give you a little more control. As you become more comfortable, you can move in closer. Remember, make the spray gun adjust to you, don't try to make yourself adjust to the spray gun. Thanks for watching and let me know how it works for you. It is a great gun.

  • Charles Feathers says:

    Thanks for the great information. I'm a HS art teacher and you learn the limitations of students and the common mistakes they make. An art term related to your suggestions of following the contours is, "line follows form." I can tell that you know students and you don't leave anything out. I have notes on your suggestions. One mistake I made before with my SuperNova was to starve the air coming off the wall. It doesn't matter if you have high psi off the wall when you have a guage on the gun.

  • Car Addict Garage says:

    Hi Charles, thanks for watching and commenting!

  • Car Addict Garage says:

    Good Luck!

  • tony smith says:

    should i use one gun for water base and another one for enamel or one for all?

  • Car Addict Garage says:

    Yes, I would recommend it. If you clean the gun very good you may be able to use one for both, but it is not really recommended.

  • tony smith says:

    thank you! thats what im going to do, one for water base and another one for enamel and a cheap one for primer.

    last question, i notice you prefer 1.3 for water base, me two but what you recommend for enamel 2.0?

  • Car Addict Garage says:

    I use a 1.3 for waterborne base, solvent base, primer sealer and clear coat. I use a 1.8 for primer surfacer.

  • Travis H says:

    should you look for 22 psi on the gauge when you pull the trigger? Or while the gun isnt spraying?

  • Car Addict Garage says:

    I prefer the 1.3 if it is going to be for both base and clear, but that is just my preference. I think either one will work good for you.

  • Car Addict Garage says:

    The 1.4 works real good for clear. If using it for base coat, you may need to decrease the fluid a little more when spraying. I prefer the 1.3, but there are many who prefer the 1.4. If you have done a lot of spraying, I think you will adjust to the 1.4 fine. However, the 1.3 will give you a little more control if you do not spray often. Either one should work great.

  • Car Addict Garage says:

    Yes, you can put a different cap on it. It will take the needle, fluid tip, and air cap to change it from a 1.3 to 1.4.

  • Car Addict Garage says:

    Yes, thicker coatings such as primer surfacer recommend a 1.6 to 1.7. That should work fine for that. The 1.3 will work for primer sealer, base coat and clear coat. Thanks for watching and let me know if you have any other questions.

  • chadatwork says:

    Donnie, I am new to painting and have somewhat of a limited resource on buying equipment until I find out for sure I can produce the results I want. I have bought the Devilbiss Tekna Copper gun, it can with both 1.3 and 1.4 tips. I know it is supposed to use less air pressure then other common guns. My question is have you used these and if so what do you think of the results? Thanks and I really enjoy your videos.

  • MrBikedrummer says:

    I just subscribed to your channel. Great stuff. I have a general question: Regardless of air pressure/tips and gun variances, what is a good rule of thumb for determining the amount of air pressure and paint flow you want for a good spray?

    I have done combinations of high pressure and played with the paint volume as well as low pressure. I am not sure what an optimum mix is because I can make them both look ok. I would like to be able to judge good mix based on a spray sample. thanks

  • Car Addict Garage says:

    I have a web page with more info. but I can not add links on here. You will need to replace the (dot) . collisionblast(dot)/2012/11/17/spraying-painting-tips-how-to-adjust-a-spray-gun-to-produce-professional-paint-job/

    See if this helps!

  • StealthShadow5 says:

    Butler which is the best air compressor for one guy who will start in this business I mean how many cfm @ 40 psi I need? I know whit a cheaper compressor the gun I will use is a lvlp. Waiting your answer and thanks for your free videos Ps:sorry for my English

  • Car Addict Garage says:

    The best thing to do is to ask your compressor salesman what tools you have and have them help you calculate the compressor size you will need. Tools like a DA sander will require more air than a spray gun.

  • anwar ulla Khan says:

    sir i am using liquid spray coating machine. i am not getting proper spray. what will be the pressure and liquid flow to have a smooth and proper coating.

  • david vestnes says:

    Good Video propely good settings for The low presure Iwata Supernova !
    But What would be a good setting for the new Iwata Supernova Hybrid.iwata says something like 26psi and full fan and full feed. A local auto paint shop have the hybrid iwata and they use 30psi and full fan and feed but they say its on the edge of running.would 30 psi be to much if I lower the feed and fan ? anyone who has a good setting for this gun, a setting where it doesnt run easy.Fan feed and psi please Thanks

  • Car Addict Garage says:

    t depends what you are spraying. I open the fan all of the way for base coat. Clear I will close the fan a little to get a wetter and heavier build. The Iwata Hybrid uses less air pressure than many other guns. I only use about 22 psi. So I guess personal preference and technique is going to play a part of it. According to the Iwata Hybrid technical data sheet, they recommend 14 to 18 psi at the gun, which creates 10 psi at air cap. Hope this helps.

  • Car Addict Garage says:

    lol… saying I need to lose weight! I agree, I've been thinking that for a long time. Maybe I need to spend less time blogging and vlogging and more time jogging!

  • david vestnes says:

    I checked again with anest Iwata The Iwata LS400 supernova is supose to be aboute 19psi while the Iwata LS400H Hybrid is supose to be around 25psi these are two different guns models Hybrid being the newest, so I guess you have the older version Ls400 which is supose to be at 19psi. you crank this one up to 22 for better atomization while paintshops who have the Hybrid version 25 psi crank theirs to 30psi for best atomization. so I guess 22 psi for LS400 is good and 30 psi for LS400H is best

    gracias me suscribo buen video !!!

  • TheChaseair says:

    Nice to listen to a good teacher

  • kujoempire says:

    can you tell us about the supplies you use. what companies and why you prefer them? oh and the youtube closed captions translator is slaughtering everything your saying 🙂 excellent videos!

  • Jefferey Hart says:

    Thanks for the really thorough runthough of the adjustments on that gun. 🙂 Mine is similar, but the cup runs through a hose before it hits the gun. . . seems like it takes forever for the material to get to the gun and start spraying. It throws me off when I'm setting it up sometimes. (It's my mom's old spray gun from the 70's)

  • Ruggeri Music says:

    Ive seen better spam from a can!

  • ghostranger96 says:

    You really do a good job explaining everything. Its cleared up so much and taken alot of the stress away from doing body work for the first time. Thank you

  • #countryboycansurvive says:

    Might not be part of what you intended to touch on, but the over lap of pattern is something might want to add. And how it has to change when spraying a solid base, apposed to a pearl, or metal flake base.
    If you release the trigger all the way, make sure to pull trigger when restarting, pointing away (off to side) of panel so you don't get a burst of build up at the starting point. Especially with pearls.
    Always test pattern first on scrap, or wall.


    damm phone wont play this video

  • cody N says:

    hey dont ever use supplements to try to lose weight. EVER. i was using them for a while now, and now im stuck with a premature articular contractions.if you stop taking them you will gain more weight

  • Coolride17 says:

    After awhile you can just hear if the pressure if right or not.

  • computerphonic says:

    Very informative, thank you.

  • Tomas Richards says:

  • Hitman799 says:

    Hahahahahahahahahaha so true Thomas

  • clockman47 says:

    Good information, i went to body back in the 60s in HS forgot a lot, THanks.

  • Bruni Auto says:

    Hey, I'm painting my car hood but the paint is rough instead of smooth, why is this?

  • Car Addict Garage says:

    There are several reasons, but too much air pressure is a common problem for this. This creates too much overspray that lands on top of the paint. You may also check to see if you are using the correct reducer for the temp. I hope this helps. Thanks for watching! Visit my channel and watch my guns spraying techniques. That playlist goes in more detail than this video.

  • SHOWMONEY5 says:

    awsome video A++++++ your tip honestly helped me yesterday on an exellent paint job not bad for my first time i loved it

  • rob b says:

    great video, thanks mate

  • King's Raajput says:

    plz tell me sir about what is PSI?

  • Jack Black says:

    I love you Donnie Smith! thank you for being so kind and showing this.
    I wish I had a friend like You.

  • Jack Black says:

    I purchased the Sharpe Fx 3000 1.3 cap you recommended.
    I called manufacturer he said to set pressure 29 PSI "at the gun"
    You recommend 18-22. What should I do if I am spraying Refinish Solutions Urethane Clear over Matrix urethane basecoat? thank you kindly

  • Derek McCoy says:

    I'm still lost with all this psi crap. I have the same gun, what do you mean "psi at the gun"? My regulator is on the gun, just like yours. Do I set it with the air control fully open? It says 90psi when the trigger isn't pulled, then 20 psi when it's pulled. Does that mean it's getting 70 psi (90-20)? If I close the air control a bit, I can get it to 30 psi, but I can also close it more, open the regulator a bit, and still get a 30psi reading but the amount of air coming out is completely diffe

  • S H says:

    I was wondering the same thing. Watched other videos and the way you set pressure at the gun is – with no trigger pull the pressure on the gauge is the line pressure ( say 90psi) Pull the gun trigger half way back and the gauge may read 45etc. With the trigger pulled half way, adjust pressure to what you want at the gun 22psi etc.

    If you set pressure to 22 etc. at the gauge without pulling the trigger, you are going to have nearly no pressure at the tip.

  • Car Addict Garage says:

    Sorry I did not make that clear. But you are correct, you want to adjust the air pressure when the trigger is pulled back.

  • Collision714 says:

    Would you used it for both base and clear??

  • jeromecarfan says:

    I really like your videos. Very educational

  • 420sonni says:

    i use the ls400 silvertip for seems to paint to slow for my style of painting. which is faster and thicker walking that thin line between a run and glass. would the 1.4 be better or would raising or lowering pressure help.i was told open fluid all the way up. where you say crank it in 4 times.need help

  • jc smoove says:

    At the shop I work at we use a 1.2 for clear

  • Dana Manley says:

    Thank you! after 30 years I decided to try my hand at a gun again after resorting to duplicolor cans for dings and touch up.  I have an RT Dakota I'm putting accessories on and it will be nice to shoot them properly. I appreciate the review!!!

  • joeblackakareaper says:

    Great stuff & thanks for the help . I'm getting a sprayer today to do some plastic motorcycle parts .


  • ROB BUSHEAY says:

    thanks my man…….I have the same gun and never knew for sure……kinda nice to know as I've been painting things forever……lol……I have been off on my pressure…..oppps

  • effsixteenblock50 says:

    Hey I'm not an auto painter, but I've shot hundreds of doors / jams / assorted millwork with alkyd oil through an HVLP, and your tips are right on the money, especially about the speed / distance thing. And of course, the best way to "get it" is by puttin' hours on the gun! Thanks for these great videos Donnie!

  • Don Saxon says:

    Thanks Donnie for all the advice…I have only painted about five cars over the last 20 years and they were all mine..a few looked good and a few looked like rattle can..I now have a big white 91 oldsmobile station wagon and I am ready to paint it a satin a gallon of black urethane primer and a gallon of Summits hot rod black satin acrylic urethan..using a cheap gun with an unknown tip size..I plan on setting up some test panels to try and get a good pattern and see how it looks..I know because of my lack of skill and professional equipment it will not be close to perfect but if I can get a uniform color all over even if its not as smooth as I want I will like it..

  • Kevin Coontz says:

    Thanks for the info, I grew up working in a body shop and learned a lot. Now  34 years later I am learning how things have changed and doing it myself ! You have great videos and explain in detail which is so much appreciated. Thanks again and keep up the good work .

    interesting points ,if anyone else wants to learn about how to spray car paint try Sovallo Auto Painting Fixer (do a search on google ) ? Ive heard some interesting things about it and my colleague got cool results with it.

  • Stan Howe says:

    Love your video's, you've taught me a lot already. Thanks. I'm in the planning stages for body/rust repairs and full paint job on a daily driver. I have a porter cable HVLP gun that i've used for spraying lacquer etc in wood working. It only has a 1.5mm nozzle and It is an obsolete gun and I can't find any more nozzles. I'm looking at using the Eastwood, 2K surfacer, and their Epoxy primer, followed by urethane base and clear. Eastwood recommends I buy their Contour LT gun and 1.3 and 1.7 tips. I think I remember you saying in the Mustang video that you used a 1.4 for everything. Do you think I have any chance to make the 1.5 work or should Pony up for the new gun.
