Has anyone ever used any of the Cerakote coatings before? I see they make a Chromex one which can be polished like aluminum as well as black and other satin colors. I'm thinking about doing my exhaust in either chrome or a gunmetal. They also have a heat dissipating coating that I thought about for the engine but it has to be baked on at 500-600F. Not sure if that would cause problems baking the cylinders, head and valve cover.
Anyone have any experience with these? Price? Durability?
