I've heard others having issues with the ceramic by jet hot and another I can't think of right off hand. I'm trying the Zybar after speaking to them and asking questions on their testing and since I don't know anyone else who has actually used it, I will be the "guinea pig" to say with confidence in helping others; yea this sucks or it doesn't.
Actually, I've heard very good things about the durability of rustoleum high heat/BBQ grill paint, but it does nothing for reducing radiant heat which is what I'm trying to address without wrapping my headers.
As far as 50 bucks for shipping...mine were 70 one way. I guess it depends on where you live and where your shipping along with rates that seem to be climbing lately.
