I am cleaning up a nice Colt Commander for a friend. He bought it in a pawn shop. On one of the side slabs, it had some words engraved and the pawn shop ground them off. I have most of the grinder marks out, but I think it probably has electroless nickle on it. It shows a pink undercoat between the finish and the steel. Any ideas on what it is? Also any recommendations for refinishing the slide? I was going to bead blast it once I finish polishing it out.
Thanks,
Craig
