I have a 70 chall conv. the new floors, trunk floor and unibody that was replaced a while ago. Of course they have much "surface" rust. I will be doing most of the resto myself, What would be the best or easiest way to derust and finish off the underside, and interior floors, get it sand blasted? chemically striped? The outer body is in very good shape. I've seen a tilting frame that is attached to the drums and rotors that makes it possible to tilt the car on it's side.
