The frame and sheet metal are for the most part, rust free. There is the normal collection of greese/dust around spring bushing areas and any other zerk fittings. I have scraped/wire brushed most of the excess in these areas.
As far as the frame is concerned, it sounds like maybe I am close to sanding.
What are the pitfalls of sand blasting the sheet metal of the body? Will it be the same as the frame eventhough the sheet metal is thinner?
