Thanks to this guy my GTO turned out great. The local paint shop wanted 3000 $ just to spray it, not including material. just material cost me a little over 1000$ and I did it myself, and I couldnt have done it without this guy, he doesnt waste time with anything that doesnt need to be said, .

I like the fact you explain the reason behind everything. For me that’s what a good teacher does.

This is one of the best automotive channels on YouTube and Brian should have multiple awards on his mantle.

Thanks brian my 12 year old and my 15 year old just painted the body on my 69 camaro by themselfs with your videos on my driveway and it came out better than 15 years ago that was done by professional thank you

Decades ago when I was painting, I mounted a true pressure regulator on my guns, not just a variable restriction valve as we see in the beginning. This was long before HVLP was invented, but maintaining the exact pressure to get perfect fan and atomization was just as important. With a true pressure regulator the difference indicated with trigger off, and full air flow, is virtually the same, not high pressure off, and way lower with flow. Setting the spray pressure with test pattern as we see here is a critical skill to develop. It only takes a few moments to adjust and look, adjust and look, then get to the job. This is a fantastic video! Makes me want to paint again, after 30 years away from the craft. I was part owner of a hi-fi speaker company. I painted thousands of cabinets with everthing from full automotive finishes to classic clear urethane clear wood finishes. Also painted guitars for a few luthiers, solids and metallics, even metal flakes. Lots of fun with the custom stuff👍👍

I loved these type of videos, especially if you don’t paint everyday or do it for a living. I may paint 2-3 panels a year. Lots of good reminders and tips you forgot about. Thanks

[JackHeuvel]

you are a great teacher. you explain everything very well. just spent my whole weeked watching your videos and tossed everything out of my head that i thought i knew about painting and starting over now. but its not a bad thing to just take a step back once in while and relearn something i like to do
thank you for all your great videos and tips

[jackwagonsunited]

Dude, I watch your channel exclusively. I am done watching backyard auto body since I found you. Great job explaining detail. My daughter and I are restoring a 1988 Bronco she bought. I am in the middle of body work and constantly watching your instruction, in preparation for the upcoming paint. I feel confident that it will be a great paint job, thanks to you. Awesome channel. Thanks Bro!

First, I love your videos. You mention that the DV1 sprays at a lower pressure but I noticed the digital gauge is close to the air cap. I recall taking a seminar years ago and I think it was PPG that gave a very low PSI rating and the instructor explained that this low pressure was AT THE AIR CAP and then explained that no gun (at that time) had the ability to measure pressure at the cap therefore the tech sheet psi was very misleading and was causing problems for people. I just went online and found the manual for the DV1 and there is a chart in it that says that inlet to the gun of 29 psi equals 15 psi at the digital gauge. So in reality, it doesn't spray at a lower pressure, it simply displays the lower pressure which is present at the air cap which is something all guns could benefit from in my opinion as it removes the pressure drop between the two which would be different for each gun.

Thanks for your videos. I am painting my second car now with your video help. Mine isn't coming out as good as yours but for having a cheap gravity feed gun, painting outside and never painting a car before, I am quite pleased with my results. I have had project cars in the past that I never finished because I was to afraid to paint. But listening to you, don't over think it, it's just paint, made me do it. This one is a van I am painting 2 tone. If you haven't already, you should do a 2 tone video.

[jimaccomazzo]

I have only painted, 2 of my own cars . Soooo awesome to hear, a “PRO”, explain proper gun pressures. “THANK YOU BRIAN” 🏆

[MarcBchannel]

Awesome vid👍 Like you say, "Don't overthink it, it's just paint". I'm just a self taught home painter and when I first started I stressed alot about what gun to get/what psi to use. I now look at what material I'm using, the viscosity taking into consideration how much it's thinned/mixed, the temperature of the material, ambient temperature, using an appropriate tip gun, and adjusting the psi/fan/fluid to get the right pattern/atomization. Spray guns are not complicated. They all spray paint they just have different tips and air caps that change the placement and size of the airholes. Some are better at certain jobs than others but all basically do the same thing albeit with some workarounds and fine tuning. I guess it is alot for beginners. I appreciate videos like this that break the info down for the beginner and a refresher for people who don't spray all the time like me👍

[Tb_Custom]

I have been learning custom paint for a long time, the amount of benefit I have found from this guy is huge and in a short time, ❤❤❤
also what makes giving a perfect psi number more difficult is the condition of the paint in terms of whether it is too thin or clotted

[bosshawg]

Awesome demonstration! Looking at the edges really made a difference in the changes made.

Excellent video!! As always Brian it's great how you go into so much detail, you are an outstanding instructor not only for diy people but also the men and women stating out in the trade. Keep the videos coming Thanks

[JVR_Funwithdesign]

Great video as always Brian. One thing that I think it is very important for people to understand about the DV1. 

It isn't that the gun is somehow magically able to spray at very low pressure, it's that the gauge on that gun is reading the pressure higher up inside the gun vs at the inlet. The inlet pressure from the wall is going to be similar to most other guns.

If you were to use the version of the DV1 that doesn't have the digital gauge and wanted to use a traditional gauge at the inlet or on the wall, you would set it up as Brian is demonstrating for guns in general (22-25psi to start).

[storyslamoxford]

I'm really enjoying these videos, as I prepare to rid myself of the '93 Capri that's been taking up space in my barn for six years. One thing, though: your motto is "don't overthink it; it's just paint." And then every word out of your mouth contradicts that!

[johnsmitht]

I'm a hobbyist watching these videos (using an Iwata PS-290 and spraying small items) and seeing the same thing with droplet size, the larger droplets are just not blending well together. It's such a fine balance with the air pressure, paint viscosity and spray distance/speed. Thanks for the explanations.

[theSilvioRoesler]

Hey Brian thank you so much for posting these tutorial videos! You are a natural teacher, and I can follow 100% of your explanations in the first time I watch

[timvandergriff]

Hands down this is the best explanation I have seen for gun pressure.
