This is back from the media blast shop. Exterior body has been DA'd to remove scuff and get ready for DP90 epoxy primer.  Car has new GM full quarters, spot welded in all original locations, including brass in key points as done by factory.

I may add a tech article later on about full quarter installation. There are several people who think that full quarters can not be installed without leaving seams that show from the inside. This is not true. Rear quarters can be installed and look exactly like factory when done. Even if you crawl inside the trunk with a flashlight.
