Just called a local guy about blasting the frame and bottom only of a monte carlo. He gave me 5 or 6 hundred dollars as a price if all was disassembled and clean, not greasy. I have a 46 suburban and he told me $50 to $100 to blast the rear clamshell doors. Just the edges and inside. Not a good idea to blast larger areas prone to warping.
