Not sure where you are located but Custom Concepts Performance Coatings -
www.CCPcoatings.com is located in Detroit, MI but ships parts all over the US. They've been ceramic coating for nearly 15 years and offer about a dozen different colors / varieties of ceramic coatings that are good for 2000F+ because they specialize in a lot of high temp turbo and supercharged applications. I know a lot of the shootout cars use them.
