Hello...

I searched here and found a post about coating copper jewelry with something specifically made to protect it (and the wearer's skin). What I'm wondering is, how do you all think using clear nail polish on a silvertone metal (locket from Michael's) would work? I want to keep it from changing color since it's not real silver, as well as protect the wearer's skin in case it leaves a mark. Has anyone ever tried this and did it work out well, and last for a long time? For what it's worth, I've used colored nail polish on metal before (usually buttons or barrettes) and it worked great. Thanks!
