Awhile ago, I stripped the slide on my JHP. Masked off part of it & painted the slide & the grips. Got the gun out of the safe today & noticed a fingerprint on the polished part. Was like it was tarnished from my skin. It came off with a little oil & an abrasive pad. (Ultra fine) I made this gun to look like the 380 with the polished slide. My question is, does MOM put some sort of clear finish on the 380"s slide?
