I just sanded down my exhaust and exhaust manifold and sprayed about 2-3 coats of this black heat resistant spray paint. Forgot what brand it was but the can said it can withstand upward temperatures of 1200f degrees. I did this because my stainless exhaust and manifold were quite rusted and didn't want rust holes to burn right through them. What I am asking is did I do the right thing using this spray paint and it will not burn off? Also if it does work will it also help disperse the heat through the pipes and out the muffler.
btw, the can cost me about $5 but I'm too lazy to dig through the trash to check for the brand.
