I like the vintage look of some of the metal where the bluing has rubbed off. I don't see any rust but with the metal in its silver state wouldn't it be more likely to rust? I'm thinking that if I keep a coat of clp on it it would be ok do you guys concur? Here's a pic I posted in my last thread but it shows what I'm talking about. The receiver has mostly black but all the other metal is pretty much silver.
