I remember corresponding with you back when you had the Visi-Flash site!
For what it's worth, I had seen a beautifully restored TG up for sale, and I asked the seller what kind of paint he had used.
Granted, this was an Embury version, but he had done what sounds like "the dip", then used Rustoleum Gloss Protective Enamel #7765 Regal Red. It looked great!
Good luck with your project!
(Maybe you can post some before and after pics?)
