Ceramic Coating

I can't speak to the JetHot finish or warranty except to say that my own 340 headers were coated in their black finish several years ago and still look great (but I haven't put more than 3 miles on them either).

The Performance Coatings finish that I'm doing now is fully warranted for three years by the coatings manufacturer. To my knowledge, the only thing that will void that warranty is running your motor on a dyno. The manufacturer recommends that you use only stainless steel bolts on the headers/manifolds, and on the valve covers above them, because any developing rust can transfer to the ceramic finish (but it comes right off with some good chrome polish).

You didn't mention what size your headers are fwaugh, but I'm pretty sure I could beat that $300 price tag you mention, your headers would be recoated both inside and out (an important fact that I forgot to include in my first post, and something I believe JetHot charges extra for), and you could be assured of being happy with the finish for at least the next three years and probably a lot longer.

I won't pull your leg and tell you I know everything there is to know about these ceramic finishes because I don't -- I'm just getting into it myself and don't have any experience to fall back on. What I do know is that Performance Coatings has been in business for over 20 years as the 'quiet' competition and, if they didn't know what they were doing, they not only would probably be out of business by now, but I wouldn't have voluntarily associated myself with their products either. If they don't look good, then I don't look good. That's how much I believe in this.

Don't hesitate to ask if there's any other questions. If it's something I don't know, then I'll find out.
