First off, I am no professional paint and body person but I would do like suggested here. Get some recommendations of who might take it and do good work and go talk with them with photos like you posted here. Any paint job laid down is going to rely completely on the prep work and once you cover it all up with epoxy the body shop may take most off to make certain what is under it is up to par. Or, they may tell you to go ahead and hit it with some primer to hold off any surface rust and let them take it from there.

Good luck and, of course, we want photos of the final product!
