I did it the easy way.
Got a 15 year girl (my daughter, her car) Gave her a couple soda's, three days, a box of razor blades, a orbital sander and about 50 or so 80 grit sanding disks, some electricity and vise grips for the razor blade. Some safety instructions, a radio with her music and guess what.....
Three days later I had a shell of a 68 GTo HT down to bare metal. Man that was hard work for me
