I see guys on these forums doing some unreal stuff...Full floor pans, quarters, cowl panels, etc. I have never taken a car down that far. I've done quarter skins, partial roof skins, floor pan patches but not all on the same car.
I simply patched in and replaced a taillight panel and did some bodywork. The car was really solid to begin with. It was sun baked from Redding CA without a single bit of rust.
