Removal of the body panels and repainting would be best option.
The only body I had to repaint was an Olympus RC that I had fixed (stuck aperture ring). Areas had chipped and scratched and had rust. I sanded out all rust and I masked lots of areas off with tape and used automotive spray enamel to get a nice black. It didnt keep well. I had to redo it with a modeler's enamel with a small brush, which finally worked well.
