I've had 2 sets of headers coated with the metallic-ceramic coating. I've also used a coating called Gun-Cote or Gun-Kote (don't remember which way they spelled it now)and hi-temp header paint. Of all of these coatings, the metallic-ceramic is unquestionably the best. I had a set of Hooker headers with that coating, and the headers wore out before the coating did. I'm now running a set of Pacesetter headers coated with the metallic-ceramic silver, and they still look great after 3 years. The ceramic coating is more expensive than other types, but it's well worth the money. If you ever have an exhaust coated with it, you'll never want to use anything else ever again.
