Working on a patch panel for the tail of my Right Rear fender. Pretty big rustout, so I cut a 6x13 inch piece of sheet metal and went to town with a mallet and sandbag. It's getting there, but still a ways to go. I may have to put a v-notch in it and weld that back together to get it to curl around the rear of the fender. It's my first attempt at forming a compound curve and I may have gotten too much curl in the short dimension.
