Ohihunter: My 642 started wearing it's finish off on the left side where my left thumb would ride. The appearance started to bother me, (I'm just funny that way about my guns). I contacted S&W and they said to send it in. They refinished the gun for me and except where the SN is on the grip, it looked brand new when I got it back. The Rep on the phone made it very clear... they'll only do this to a 442/642 once. Cost me shipping, nothing more and I think it looks great. Since I carry this gun quite a bit, I'm thinking ahead to the next refinish job at which time I'll consider either duracoat or cerakote. In your scenario, I'd call S&W... couldn't hurt. Hope this helps you out some.
