I'm probably got spray it with red oxide rustoleum primer. Its 10 bucks a quart and sprays like a dream. I will drive it like that until I can start the bodywork. That's the primer I used on the floorboards and under carriage in sprays and covers wonderful. I am gonna go ahead and paint the engine bay and doorjamb now so I don't have to pull the engine and interior whenever I do start the bodywork.
