restoration

Hey guys. I'm trying to restore my Juliet. I want to keep the same finish (Carbon) or something close to that, but I don't know what kind of paint I must use. It's the first time I try to do this, so if you have any tips or any experience with this processes, please share, it will be welcome.

My dad recieved a pair of Mars sunglasses as a gift from a friend for a construction job that he did in the Hamptons. For those who know this story, I'm sorry to disappoint but there was in fact a seriel number... my dad's eyesight just isn't what it used to be. Anyway, these things are 2...
