I used this paint to coat my intake manifold, intercooler, turbo and brake calipers. It has held up great on all but the turbo which reaches approximatly 750*. All items were sandblasted, and throughly cleaned before coating. The brakes are the next hottest item at around 275*, and they've lasted 3 months so far. I run a small powder and ceramic coating company, and used my own car as a trial, and will be not for any customers parts. With a little research you will find a much better product for about 50% more.
