Tech Line makes some good stuff.
All hot parts should be reflective (chrome = good) and light-colored (silver, white, aluminum) to retain that heat energy, and reduce under-hood temps.
I used cerakote on mine. No results yet but as a person in the coatings industry I can say it sprayed very well and leaves a very nice hard and durable finish. I've banged it around and even took my map gas torch to it and no blistering or anything. I also wrapped it to help hold the heat in even more.
Is the cerakote stuff, the stuff you have to be "in the industry" to buy it? I can't remember which one I looked at, but read great reviews on it, contacted them, only to be told, I had to be a powder coater company to buy it. I thought about banging out a small llc just to buy their crap, but sounded like a little too much work.
I’m not sure whats in the rustoleum BBQ grill paint but it plain works. I’ve used several spray on coatings like VHT and none of them hold up like the BBQ grill paint. It greys a bit, but keeps the metal coated and free of rust. I literally ran my turbo buick manifolds 6+ years on the stuff and never had any finish issues. I use it on all my turbo hotsides as well. They have flat black and ultra which is more of a satin finish. I usually spray and then wrap my mild steel hotsides. Then spray it again.

Like all of Swain Tech’s coatings, White Lightning™ is a performance improving coating. What makes White Lightning™ the best performance exhaust coating?
White Lightning™ really is ceramic so the material is a superior insulating material.
White Lightning is applied much thicker than any of the cosmetic coatings. White Lightning™ is applied about .015” thick compared to about .002” thick for the cosmetic coatings. Because White Lightning™ is the best insulating material and it is applied thicker than any other coating, White Lightning™ offers performance improvements that cannot be matched.
Many companies apply the shiny or colored paint based coatings and call them ceramic. Those thin shiny coatings are very different than Swain Tech’s White Lightning™.
Whereas it would be more accurate to call those thin shiny coatings good high temperature paints that may have a very small amount added to them, Swain really uses a ceramic coating that is applied molten where it bonds and cools directly on the substrate.
