I work in the bodyshop of a high end dealership. Some of the guys here have done rust repairs on older cars. The guy who did high end restoration and fab work (Dusenbers and such) is no longer with us.
Unforunately, most of the guys in the shop want perfect parts to work with and don't take any interest in forming panels themselves.

I thought I'd toss it out here and see what you guys had to say.
I might be able to grab a section of roof off a current car to patch in.

What are the chances of the header below the roof skin being rusted through? I don't know that I want to get into patching structural stuff.
