Jet-Hot offers a coating that looks like freshly cast iron. The coating is
ceramic in nature and does not discolor due to heat. It is also very chip
resistant. I have read several favorable articles about the process and I called
Jet-Hot and they quoted $125 for coating an exhaust manifold inside and out. They
offer several other colors one of which is black.
