  1. Orange cap is 1.3 mm – Good for base coat and clear coat. Silver is 1.4 mm – Good for clear coat and primer sealers – Purple is a bigger cap for things like big metal flake, etc. I personally like the 1.3 for base and clear. Some people prefer the 1.4 for clear. It just depends on what you like better. Let me know if you have other question. Thanks for watching!

  2. Yes, pearl is very fine. The orange should work great. You may need the bigger cap when painting big metal flake like on boats. Thanks for watching!

  3. To everyone out there that is learning how to spray paint , trust me this guy knows what he is talking about , these are all the correct techniques to become a painter and a good one at that.

    very good video mate from england 🙂

  4. Thanks for taking the time to make that video. I have a better understanding now of adjusting the spray pattern and whats up with the pressure at the tip verses the gun. Thanks that will help me a great deal. One question Im thinking of getting a LVLP Gun because I only have a 5 hp compresser and it runs all the time. I hear that a LVLP gun will help reduce cfm. Willt he results still be similar and will I need to go slower with my stroke when laying down the paint? Thanks so much

  5. We buy from Keystone Automotive and Car Color. If you are looking for PPG, there should be a paint store near you. Thanks for watching!

  6. We don't use one, but our filtration system is pretty good. If you are having any water or contamination problem it may be a good idea to have a filter at the gun. Thanks for watching!

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

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

  9. 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!

  10. 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.

  11. 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.

  12. 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.

  13. 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?

  14. 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.

  15. 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.

  16. 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.

  17. 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.

  18. 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.

  19. 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

  20. 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!

  21. 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

  22. 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.

  23. 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.

  24. 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

  25. 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.

  26. lol…..you 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!

  27. 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

  28. 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!

  29. 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)

  30. 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

  31. 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.

  32. 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

  33. 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.

  34. 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

  35. 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

  36. 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.

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

  38. i use the ls400 silvertip for clear.it 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

  39. 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!!!

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


  41. 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

  42. 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!

  43. 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 black..got 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..

  44. 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 .

  45. This is my recommedantion for corbandy car sprayer crusher, try to google it.Search car spray painting guide.

  46. 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.

  47. 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.

  48. I am getting ready to spray Nason single stage urethane with an HVLP gun. The can says to set the psi at 8-10. From what I am seeing online is anywhere from 14-20 PSI. Which should I use as a starting point for my test panel? 8-10 PSI seems a bit low.

  49. Thanks for the help on understanding my Iwata LPH-400 sprayer.!!!! I definitely like the idea of the disposal paint bags!!!!!! No wonder everyone but mine still looks slightly dirty after I use it!!! 🙂 Got me to Subscribe!!!
