I can't direct you to any particular product but can relate a little technique I found to work with high temp paint. After painting a manifold (black) for the first time I ran the engine and after a run on the road opened the hood to find the manifold turned white. Next I repainted it with the same product (too many years ago to recall) and ran the motor for just a few minutes--not to full hot-switched it off and let it cool completely--after that the paint stayed in good shape for a long time. Hope that's of some help. -- Dave
