After wiping it all down with laquer thinner and wax and grease remover, I hit it with 80 grit on the DA and it cleaned real nice. I had to go around with 50 grit Rolocs and clean up some pits but they weren't bad at all. The worst part was the huge amount of little dents all over it. It looked as if it played target for a BB gun at some point. There was also a 1 1/2 foot gouge down the side that was about 1/2 inch deep. I went through over a hundred pulling studs getting it all straightened out but it came out real nice.
