I am a big fan of any color Rustoleum sells in gallon pails, myself. :) I use a sprayer and spray it on real thin, several coats, polish like ordinary automotive paint and it's real shiny and real cheap to repair.
There is a lot of write ups about this on the internet. It's how I was going to do the Jeep, but the paint is still so good I don't have to worry about it. I did the bus that way though.
