I painted my headers with high-temp black (2 coats) then wrapped them two years ago. They have seen many heat cycles and extreme temps and are in perfect shape. I have heard bad things about the wrap, but I haven't had any issues. The only thing I did not like was the initial burn in, they smoked and smelled pretty bad for about a half hour. On the good side, there was a noticable reduction in heat under the hood. Just my .02
