Spiff up an old gun for display?
I have an old nonfunctional gun I'd like to hang up. It's completely trashed and has no value except as a conversational piece ("How long were you tripping on THAT piece of junk before you put it on your wall?").
The finish is worn off unattractively in some spots and there is some rust. Would it be terrible to put oil or wax or something on it?
Any advice is welcome! (Just don't advise me to polish the brass!)
