Airbrush Touchup

Does anyone have any experience with airbrushing auto paint? I know we have some guys who do some cool work, and guys who paint, so I'm hoping you all could help me out.

I just bought a nice (highly recommended) airbrush kit on Amazon. I'm looking to touch up some small scuffs/chips on my 68 Camaro, as well as a few on my wife's 06 Mastiff, my K9 etc. I have the paint for the Camaro (base/pearl/clear) that I got matched by Napa (they have this cool digital machine that reads your paint!) and the color is perfect (have same for K9 and Mastiff), but putting it on with the brushes in the little bottles is a pain and comes out terrible. I have experience with an airbrush, used to paint models and such when I was younger, so I'll sort that skill back out. I'm mainly curious on how to thin the paint so it's that 2% milk consistency that you want to air brush. I'll of course do some test runs on bottles/cans etc. to get the flow right...main question is really what to use to thin it and maybe any other tips. Small spots, most less than pea sized or smaller.

I also picked up some Bondo paint chip repair stuff at the recommendation of the paint guy, it's a two part and he said to mix it up, fill it, then sand it smooth. I did that on a few spots and it looks great (nice and smooth, no more chip), but when you add the paint on top with the brush it goes on way too thick and looks like crap.

Not sure if I need to use 'paint thinner' or 'lacquer thinner' or what really...

Thanks gents!

All I can recommend, practice on some other objects you have laying around, also use “guides” like 3x5 cards etc to keep the overspray off places you don’t want it. Don’t let them touch the surface. Mask where possible,

Thin using the matching thinner for the paint you have. Don’t use lacquer thinner on urethane paint for example.

Thin to the consistency it will spray well. Over thin and it will run and not cover, to thick it will clog the gun and spit heavy particles and not atomize well.

Thanks guys, I'll go back to the paint guy and get the right thinner! And practice practice practice! It'll be nice being able to fix nicks and such!
