I bought my gun at Harbor Freight and 40 psi worked well. I would test the pressure out the spray end by test shooting against a bord or piece of metal and adjust the pressure accordingly. I had no significant over-spray and no orange peel. I did not need to use any primer as I had no bare metal, I first sanded with a #400 wet/dry paper and finished with a #600 wet/dry ( all you need to do is ensure that there are no glossy spots). I washed her down with de-greaser I bought at Sherwin Williams and the first coat I shot was a tack coat (a quick once over at about 12" above the surface, the rest of the coats were shot at about 6" above the surface and a little slower movement). I waited about 10 minutes between coats and after shooting all the color, I cleaned the gun (paint thinner), waited about 45 minutes before starting the clear coat (not over 1 hour) and did the same routine as the color, both in a tack coat and the finishing coats. The trick I guess is to keep the gun moving and give a little overlap on each coat. I will admit I had a neighbor who restores Older VW Beetles looking over my should for the first shoot and then he told me I was doing fine and walked away. I was nervous, never having done this before, but the reults were great. Any more qyuestions just ask or email me at
