Consider an auto body class at your local college. Most will even have a spray booth. The teacher surely will guide you in the right direction. If you can work a wrench surely a grinder falls in that catagory. My friend just used glue to install his quarters on a cutlass. Seems this is the new method to panel installation. Surely you can glue in patch panels. My thought is at least you will know what you have. A skilled body man can make a rust bucket look perfect for a couple years. A car purchased to be flipped never gets the attention a keeper does. Cut it, patch it, learn a few things, sand with a long stick, and then proudly say YEP DID IT MYSELF! Body work is patience. My friend with the cutlass first held a spray gun in his hand shooting POR inside my fenders. His car is beautiful now!
