AirBrush Paint Chip Repair?

Well I got almost everything, I'm still waiting for the spare bottles I ordered and the moisture trap for the compressor line.



I went to the auto parts store and bought some rattle can paint, clear, and primer to use for practice for now. I have some sheets of sheet metal that i'm using as my canvas. I have been using the #3 tip, but i also have the 1 and 5. I have been playing with the compressor between 20 and 40psi. So far lower seems better.



I think i used too much laquer thinner because the paint is very runny, this may be why lower psi seems better though, paint is too thin. A portion of the panel is looks good, but the other portion has some NASTY runs. This is a little more difficult than I initially thought. Watching someone do something makes it look sooooo easy... then you try it yourself. Still I think after a few more practice runs I will do much better.



I still need to do the clear, and I'm having a hard time adjusting the gun, but again, i think it's because i thinned the paint down way to much.



I will keep you guys posted and in the end (once i can do a decent job) I will try and provide a step by step with pictures....
 
Even using a #1 tip, I haven’t had to thin bottled paint very much. Start with a very small amount of paint (I like to use a color cup rather than a bottle for messing around) and different dilutions. Use an eyedropper (preferably a glass one). Count out drops of paint and drops of thinner.



Using the #3 setup you may be surprised how little thinning you need (if any at all). It’s not like you’re trying to do artwork, like tinting, fades or frosting. You’re covering an area.





PC.
 
an eye dropper is a very good idea, I'll go to CVS later if they're still open.



I'm just messing around getting a feel for the airbrush right now, so i'm eyeballing paint mixes. I'm in the middle of attempt #2 right now and i can tell it's going to at least be marginally better than attempt #1. I turned the pressure down to 25 psi, and thickened up the mix a bit. I think I'm at least picking up some basic technique for the job.



The runs aren't there, the paint appears to be nice and even so far. Though 1 problem is that my garage is VERY dusty and i keep getting dust settling on the wet paint.



I'm using my halogen lights to keep the work nice and warm since it's like 40 degrees in my garage.
 
my neigbor, who dabbles in airbrushing, has one of those big chemical pump sprayers (the type you would use to spray down a backyard) and sprays down his garage floor before he starts painting. Doesnt soak the floor but wets it enough to keep the dust down. He does keep his garage floor pretty clean to begin with, the water is just the "extra" step to minimize any errors.
 
That's a good idea, i wish my garage wasn't such a mess. Ideally I want to build cabinets and shelving so that I can get everything off the floor, so i would be able to spray it down.





I just finished laying down the last coat of basecoat for attempt #2, It's a good flat surface, but it is a little streaky (you can't tell from a distance, but if you look up close in the light), that's probably me not having kept constant speed and distance from the piece.
