Picture framing effect?
Anyone got any good advice for that? I tried powder coating several samples last night and after I would bring the chrome out of the oven for a transparent, I would wait until the part cooled to maybe 175* and shoot the transparent. Everytime it was coming out with a nice fat outline on the sample chips and be good coverage in the middle. I adjusted KV's up and down several times in small increments, increased gun distance, decreased air pressure, all of that stuff and still ran into the same problem. I just recently grounded my rack to a 36" copper tube and my gun is also grounded to the rack at a separate point. I get excellent powder coverage to the part but that framing effect is a killer. Anyone got any helpful advice on maybe gun settings and air pressure to get rid of this framing effect stuff?
