These cars look really sharp in black! I'm just wondering..... have you ever tried Bare Metal Foil? The chrome pens are kinda expensive, I like to save mine for interior trim like handles and such. If you have steady enough hands to do the chrome down the fins, then foiling will be a breeze!
When I was young, we had a '60 Fairlane 500..... They don't have the bubble top that these cars have, more of a sedan roof........
