I have a question that hasn't been covered in this excellent thread. My S4 has a galvanized body. What's the proper procedure for bodywork over galvanized? I'm talking about repairing small dings ect. that can't be reached from the backside. I plan to eventually paint my whole car but would prefer to not take it all down to bare metal. I've been spraying lacquer for nearly 50 years on furniture and cabinets but have never done a car.
