i wanted to roll my rear fender lips so i could fit a little bit bigger tire and not have to worry about that sharp edge touching my sidewalls. its in primer right now so i dont have to worry about paint scratches/chips. i talked to someone with a 65 fast back mustang and to roll his fenders he just beat them with a hammer till they rolled over a little bit. it looked good and wasent noticeable untill i accually got on my knees to look. i was wondering if you guys would recommend the hammer method? i just wanted to get this done now before i have paint on it and want to do it.
