One of my favorite before and after photos. The car had some serious rust damage on all four corners, patched by the original owner with aluminum, home made braces and Bondo. Here, he had brushed heavy black material as far up as he could reach and then sprayed leftover spray paint up inside to try to protect the inside of the fender. I rebuilt the original brace and patched the fender. You can see the reapir seams on the brace and fender.
