So initially, this car didn't look too terrible. Sure there were no floors and we knew that there was some bondo in the doors but....
I always like to start with the most difficult part first...in this case, it was the passenger side door. There was a large bulge at the lower rear, which initially was thought to be bondo, and extensive use of flashing on the inside.
Once the the lower section was cut off, it appeared that the skin had been dented and "repaired" sometime ago. There was quite a bit of lead and a spot where it was punctured and ripped. The bulge wasn't from filler but from the repair and the lower frame being tweaked. Once everything was cut away, the skin relaxed and fit the curvature of the repair panel perfectly.
