Hi Dan, the Z GS does have some rust issues, but nothing like the Red post coupe had. Most of the trunk is good except for the usual areas over the body mount, so those parts are reproduced and can easily be welded in and new rubber mounts installed. The stainless wheel well moldings are going to be removed and NOT going back on the GS because all they do (here in the rustbelt) is hold moisture and rot the fender lips. So I have some of those areas that need metalwork too. This GS was hit in the rear at some point in its life because it has some right rear quarter panel damage and trunk lid was a skylark lid not a GS lid, I made the correction drilling the extra hole and adding the GS emblem. Considering it does have 103 thousand miles and was used as a daily driver for many years (it has many parking lot dents to prove it) And lived here on Long Island all its life, It is a survivor.
Yes, I have used the epoxy panel bond to do smaller repairs on several vintage cars including my post coupe GS restoration project. Its a great way to permanently affix Two panels together when welding is not an option due to the excessive heat. The special gun used to squeeze the epoxy out of the Two tubes is very expensive, so I made my own out of a few wooden dowels and it works just fine.
I also make as many of my own patch panels, I find that hoods are the best way to get good flat panels that I cut into quarters and keep in stock. Hood support braces also have tight curves that I use for fender lips. Not much goes to waste here !! I have a collection of pipes, bars, pulleys, and sorted blocks that I find anywhere that I use to shape the metal. There are no fancy tools in my garage. That's the fun and the challenge,
Tony
