I thought there was a type of ceramic powder coat, but I am not very familiar with the process. I had one set of manifolds coated by JetHot, but they are starting to peel. That's not very cool (no pun) for a lifetime guarantee. It's only been a relatively short 6 years in my manifolds' lifetime. Incidentally, I've contacted JetHot several times about the failure under warantee, but I haven't heard back from them yet. Curioser and curioser. bb
