Hood prop and battery housing you can use any 500 degree paint. Nothing fancy. Most metal paints are 500 degree. Are you saying you want to paint your hoses? Bad idea. You could install colored fiberglass or CF mesh covering, which you can buy from most auto stores. Our motors dont get that hot.
I think 500 would work well for all parts of our motor (our normal coolant operating temperature is no more than about 250, I believe)
