Friarjohn a friend of mine that ran panheads used to paint his exhaust with black bar-b-q paint Bar-B-Q Black it was called. Was flat black and made to hold up to way more heat than you ever get with exhaust. It was tough too lasted a long time. Barrel paint is another one I have used for years made to paint cylanders on bikes but I was painting cylanders. I never painted exhaust on my bikes...yet anyway. Who knows the future.

I learned all I need to know about life by killing smart people and eating their brains.
