i just came up with another way on the front fenders and valance on my car the other day...a runner mallet!!!! i needed to do the valance and the lowest part of the fenders where the valance meets the fender, the mallet worked like a charm and didn't screw up my paint either. we had previously rolled the fender lips up front and the rear 1/4's but we didn't do the lower front because we didn't think we'd need to, turns out we did with 17x8 e'brock 454's and 245/45-17 falken rubber.
