Ive been having paint problems and im at wits end trying to figure it out. I first started painting last year just a small project. I bought some OMNI AU black mettalic paint and already had a old craftsman touch up gun and old well used filter from my dad. Well I tried and after I got done there was tons of little bumps all over the paint job. It would be like sand paper about the size of a pin head all over it looked like shit. I opened up the filter and there was all this dried yellow water everywhere since it was so old and the paint gun was soooo old i thought this must be the problem.
So this year I bought a cheap Astro LVLP gun and a sharp filter and a central neumatic filter and a regulator at the gun all new hose and everything and it does the exact same thing. Ive tried everything from thinning the paint more to turning up the air pressure way past the max and it always does the same thing.
It just aluminum sprayed with SEM self ethching primer, wiped down with with thinner to clean and tack clothed, and painted with 4:1:1 OMNI AU and MK168, and of course thinner.
I dont know what to do Ive tried everything it looks terrible. I dont think its a water problem since my compresesor never even ran for a couple days since it was a small project it is cool and condensed.
Heres my setup
25ft of 3/8" ID ruuber hose to cn filter to sharp filter to regulator, 25ft of 3/8" ID tube to a regulator at gun. Any help would be great. Thanks, Dan
