Hi guys, I don't get on the forum much these days. I'm sorry the coating isn't holding up for some of you. It's always in the areas with a lot of moisture and/or salt on the roads, specifically the North East. As an end user, when your coating fails it sucks. But we have built over 2000 sets of headers for these cars and there is about a 2.5% failure rate with the coatings. That's really very good, UNLESS you are one of the 2.5%. I do offer the coating as an option and tell customers they should get them coated locally if possible. As mentioned above, usually when the vehicle sits is when the coating is most prone to failure. So if you store your car for the winter, park it on top of a thick sheet of plastic, to keep the ground moisture down, even if the garage is heated. Then tuck some blankets around the headers, then tarp your car. Otherwise moisture gets under the hood, condenses, rains down and droplets sit on the headers. When coatings fail the customer usually observes rust spots on the tops of the header tubes.
Performance Coatings does a very good job otherwise I wouldn't use them. I have had customers send me Jet Hot coated, HPC coated and Airborne coated sets of headers to have Performance Coatings coat them because the coating failed. In my opinion there isn't any one coating company any better or using a superior product. It is the amount of salt exposure and or storing of the vehicle which effects the coatings.
Reading above there was an actual rot through, that's the first time I have ever been made aware of this. We do only build the headers but if there is a possibility of repairing our products due to rust, we are always willing to try. 304 stainless headers are going to hold up better and technically do NOT need ceramic coating. The cost is higher but $295.00 is usually spent on coating. I just posted a sale which would allow you to get a set of 304 stainless for what a set of coated mild steel usually goes for.
Any other questions or comments, let me know via email as I don't seem to get notifications from the forum for some reason.
