How can I make my slant six exhaust manifold look great?

Rustoleum BBQ high temp paint works surprisingly well. Have it on my daily driver for 2 years and its just starting to show a hint of rust coming through. Best thing is you can touch it up and its virtually undetectable. It comes in flat black or silver. Spray can or quart.
I have used the expensive paints with poor results. The BBQ paint is only a few bucks.

Is that a factory cruise control?
