No I'm talking about having it professionally done kinda like ceramic coated headers. The chrome headers will turn purple when they get hot but ceramic coated ones won't.
Yeah, I know what you're talking about, both 'Yeller and I do it, and if I'm not mistaken, Honeybee does it too. Cerakote is, in my opinion the only spray and bake worth using. Call up 'Yeller, he's much closer then us, and he does a really good job... and, well, he's an alright guy.
