From a recent edition of Cooks Illustrated (please pardon any typos - I had to re-type it from the magazine):
I am on round four of the above method. The only thing I did different is put my pan in the oven while self cleaning. When finished the thing looked like I had sand blasted it. Right now I can't believe how great it looks. A hard shinny glass like finish. I can't wait to try it out. Two more rounds to go.
