Re: Ceramic Black
What parts are you calling "exhaust" and what are the running temperatures? Are you coating the inside, outside or both? Coating only the outside will cause the temperature to rise in the base material. If it goes above the limit of the coating failure often occurs. Good preparation of the surface is also a must. Think of the coating as a plate. If the part won't take a plate, it probably won't take a ceramic coat either.
