Here's what I did on my 55. After the paints been removed either chemically, or with grinding discs or by blasting it. Next step to wipe down with a quality metal prep to dissolve the rust in the pores of the steel and in the pitting . This beats grinding off a lot of good metal. Next Step two coats of the MasterCoat slim silver permanent rust sealer surfacer.to help to Level up the pitting. Step 3 as soon as the second coat of silver dries apply two coats of urethane or epoxy surfacing primer. Block sand it and then you're color. This type of system will provide you with maximum corrosion resistance rather than a regular production paint job.
