I got my headers back from Swaintech coatings yesterday. I went with their "White Lightning" as it's advertised to be most effective in heat retention. It looks better than I was lead to believe it would as their sale force described it as a functional, but not an aesthetic coating. I like it. It's coarse, almost looks metallic, and I took a close up with a dime for a scale comparison. It does appear to mar easily. I haven't decided yet if I'll leave it like this of paint over it with white header paint.
