I also took the opportunity to clean up the roof skin. I was really surprised that there wasn't ANY scale on the roof! I was mainly removing a yellow glue that was all over the skin. The roof structure wasn't scaly or rusty at all. It was still dusted red from the factory. It seems bizarre that this car did so well sitting out in a field for 20+ years...I can only guess that it aired out quickly without a windshield, rear window, or carpet in it.
