I have a FM turbo manifold I was thinking of getting ceramic coated. I called FM about their coating and was told they don't do it anymore because the manifold gets so hot it starts to peel off over time. I still think some kind of coating is better then none. I called around locally and got some pricing. Some cheap, some very expensive. Then I saw at the auto store they sell it in spray cans thats rated for up to 2000 degrees. Does anyone have experience with the spray. Thanks for your input.
