I didn't have a problem with it. Other than the fact the bottom was so warped that water pools in the center. I just wanted to play with it and test out the grinding smooth theory. I didn't go very fine and I certainly ly didn't polish it but with one or 2 coats of crisco, it is ridiculously slick. I wouldn't have done it if it wasn't already damaged. Plus, now I'm using it as a trainer pan for my beautiful wife to learn cooking on cast iron. ;D
