There is a series of holes in the roof where something was mounted, perhaps a sun shade? The holes were dimpled in and mudded over. I hammered the dimples out and will weld the holes closed. Also spent a lot of time cleaning up the windshield opening. Luckily, the flange where the gasket goes is solid, but there were a few BB-size holes on the sheetmetal around the lower corners. I filled those with Fiberglass from both sides. I caught a break on that one. Rebuilding those corners would have been a difficult job.
