Initially, the frames on the DeLorean preproduction vehicles were manufactured of Stainless steel. This was an expensive chassis and JZD was quoted describing the frame, "that's not extravagance...not even Rolls Royce does that." (produce stainless steel chassis. Old Rolls Royce's' were made with wooden frames) The epoxy coating was an alternative idea to stainless. I have been doing some research removing the epoxy from the DMC chassis with RediStrip Company of Roselle Illinois. They developed an immersion process in alkaline tanks to remove rust, paint, epoxy, etc., off of car parts, such as the entire DeTomaso Pantera body. After the process is complete the frame can be galvanized or power coated again. RediStrip advertises in Hemming Motor News. Sincerely, Mike Pack DOA 4743
