I have the schell flipped over and I am ready do do some work but I am not sure what to do. Before I bought this it was sent out and the floor rewelded in, the fron frame rails were done, the battery tray and I am not sure what else. All the rusted areas were taken care of and now there is some minor surface rust. I am thinking I am going to sandblast prime, paint and undercoat the bottom. What would you do. Please advise.
