A bit of an update:
First off, I decided the interior will be stripped. The rear seats are gone and will be replaced by styrene. I'm going to remove the upholstery from the door panels.
I've finished the fenders as far as the general shape is concerned. There's still a lot more work to be done to smooth them though. I've also removed the side blinkers, and filled in the license plate cutouts in the bumpers.
If you're wondering about that rear strip of epoxy, that is the base for the ducktail. It will be classic in shape, but it will have different proportions from a regular ducktail. I'm going to make it shorter, about two times the current height of that piece of epoxy.
