I PC'd a pistol linear compensator yesterday in silver over a black coating of some kind. The powder stuck perfectly without shaking, I just closed any openings with silicone and dunked it in the powder. After tapping the comp on a tray to get excess powder off of it, I baked it. The first coat was very good but the black was still lightly visible under the PC, so I dunked it again and after cooling there was no sign of black.
A minor issue is the powder lumped / clumped / ran in spots and I would like to know if these areas could be sanded flatter or should I just strip it and try re-applying the paint? I could live with the few clumps I guess, more so than the black come on a stainless gun but I wondered if there's a simple remedy for clumps on a finished part.
