Not sure where to post this question? Exhaust manifold paint?

I used a ceramic "paint" on some Pro-parts headers and they held up well. It was white and said it had ceramic powder in it, whatever. I sprayed it on, let it flash and then let it idle for 30 minutes per the can. Worked great. Every hi temp paint i have looked at stresses you need to heat cure it right after you spray it. My Hookers were shedding their silver hi temp paint for months becasue I never cooked them. BBQ paint at 5.99 a can, why not?
