SEA DOG, why do ya wanna sandblast the whole truck? like martin sez, seldom necessary - sandblasting is for removing heavy corrosion, especially where there's gonna be metal replaced w/ welding, or for cleaning up areas ya can't get at any other way - blast the whole truck and yu'll be swearin for years as the sand comes tricklin out here and there and everywhere forever - spend the money on sandpaper and sanding aids [DA and good blocks, etc] instead of sandblaster, and take small pieces [like wheels?] to a more reasonably priced blaster if necessary
