I'm replaceing the inner and outer lower panels on my 59 drivers door. The inner panel went well and so did the outer until I got carried away with grinding the welds and warped it. I have about a 1/2 inch belly about 7 inchs up from the bottom, and 3 inchs in from each side. Did I ruin this door or can I save it somehow? Heat shrinking does not seem to help much. Any help greatly appreciated. Thanks, Mike
