I adjusted the fluid and played around with the air pressure but I only went up to 40. The best I could shot was at two turns of the needle and about 33 PSI at the gun. I thought that maybe I wasn’t getting enough cfm but my compressor is rated at 8.2 cfm @ 40 and the gun will work in the 7-9 range @ 40 psi. I did hook the compressor up to a pipe system that is ½” and I’m running it through one of those large high flow desiccant air filters but I thought that would only help me. What I wound up doing was hitting it with a green scotch pad to chop down the high point and then I was able to sand it fairly easily with 400 grit. I think if I waited a few days it might have been harder sanding. I tried out an area on the taillight panel that I shot back in May with the other gun and it was still easier than what I just shot.
This is the gun
I sprayed with the self-etching Vari-Prime with no problem. I’m going to try more reducer next time.
