New metal patches were cut and used to repair all of the rust. Good suggestion by Aurelio to use automotive structural adhesive instead of welding. That provided a clean strong bond with a neat final finish. All seams were then sealed with seam sealer. Next was 2 coats of primer, 3 coats of copper mist poly paint, new rubber plugs and gromments from Steele Rubber, and lastly trunk lining material that matched the OEM finish. The original jack and hold-down hardware was also retored in the process. The guys at Scottsdale Paint were very helpful providing PPG equivalent paints that exactly matched the OEM PPG laquer paint used by GM in 1960.
Seam sealer was used to replicate the factory application on the hips and all joints:
