What do you have for equipment, do you have a compressor that can handle painting?
Start with epoxy primer on bare metal. There are a number of online brands (I used Southern Polyurethane) but I would recommend finding a local paint supplier and buying from them. Make sure it's sandable. Do the bodywork over the epoxy, and spray more epoxy over that for a weatherproof finish.
