Hello I am doing a lot of sheet metal repair on a Club Sedan I have purchased and mocked up the repair panels but I have a problem the lip on the rear wheel wells is rotted away I do not have the tools to roll the lip and make the compound curve needed to repair the tub. Just wondering if there is a universal edge or a technique to rebuild the rotted area. I know most of the question here are engine related but I am hoping someone has come across this issue. The car has been parked since 1988
