So lets talk thermal coatings. When I had TOG headers that were JetHot coated I was not happy with the results. They were more like paint than a thermal barrier. Not to mention that by the time I got give of them and their "lifetime" warranty they were starting to flake and rust.
I have heard great reviews about this though.

I think I may rock them raw this summer and let them get some heat cycles in. Then this fall I will remove the headers and pay the money to get them coated and do the 6-8 week wait.
Opinions?
