How to roll a fender lip?

Halfafish, do you like sports? My 65 Bcuda has some damage to the right rear quarter and the lip was uncomfortably close to my tire. I bought a basketball and a football and jacked the car up. Deflated both balls and worked them in between the tire and lip. I let the car down a bit and inflated both balls. Lowering the jack and bouncing the rear oof the car gently folded the lip to gave me just enough room.
