Tony,
I picked up some literature from JC TECH COATINGS in Syracuse NY.
www.jctechcoatings.com 315 263-1206 They advertise cramic coatings, powder coatings and thermal barrier coatings. I have not dealt with them yet, so I have no recommendation on their service and product. Maybe someone can comment on them. Good luck, Keep posting pic's your and inspiration to a future A & C builder!
