This is a little different to the questions you guys generally get, but eh. . .
I'm modding my keyboard, a Dell SK-8135, it's a really nice keyboard, it's got nothing on the old Model M's, but I make do with what I have available.
Anyway, I'm using some really fine sandpaper to take the symbols off the keys. I'd rather not paint again if I don't have to, as I like the colour they already are. However, I'm trying to look for a way to make give them a nice shine again. Any ideas?
tl;dr: What's the plastic equivalent of varnish?
