Did Ford use lead on the roof? While prepping the body (taking it down to bare metal) I noticed an awful lot of scratches from my sander on the metal, then I scratched at it with my fingernail and pulled up some metal. All 4 corners of the roof have been leaded. The sheet metal parts have been crimped, welded, then leaded. My guess is somebody had a screwed up roof and used one from a donor car.
