Ok well I emailed the company that makes the ceramic paint additive and ask a couple of questions. I asked if it could be added to automotive paint and more importantly if it would block any heat transfer to the epoxy under the paint? here is there reply.
Donnie Haulk,
Yes, the Ceramic beads will mix with any paint and give you an insulating
barrier. It does leave a slight texture. With a couple more coats of paint
over the beads, the texture will be gone, leaving a smooth finish.
The ceramic beads are the same technology used by NASA space shuttle to
protect the astronauts from the 2000 degree re-entry temperatures.
They use ceramic tiles made the same way as the beads.
Your project is interesting because I have my pilot's license, and I worked
for many years as an A&P and AI aircraft mechanic. I used to rebuild
aircraft as well as maintain them.
Good luck with your project.
Well this seems like good news maybe I can have my sexy black cozy!!!
