36 vs. 80

I would never use 36 way to rough, when we were in high school my buddy bought his first car and our friend Ed was painting cars and told him if he stripped it he would paint it, Steve used a 36 grit and a electric sander and ground all the way through the 1/4 panels on the corners, the whole car was scratched up so bad it took a gal of bondo over the whole car to fill the gouges, Oh man we laughed our *** off.
