im working on a 79 cutlass salon and i found out that the entire driver side rear panel area is completely rusted and painted over. is there any way to fix the body being that this car is a uni-body or is it basically trashed. i have some holes in the frame that can easily be patched but i found this hole in the panel behind the rear wheel. basically the hole is now the size of 2 fists. i dont think there is a way to save it other than getting a new body but thats pretty much out of the option. any ideas one what to do?
