Are you willing to disassemble your vehicle to galvanize it? There used to be a place here in Sacramento that would do the whole thing, but it was a bath/dip process that would not be possible with a whole truck.

If you are that worried, keep it washed during the winter and maybe get it oiled regularly like the Canadians do. The other option is to get a cheap winter beater car and not drive the Cruiser.
