There was an article (way back) in one of the American VW > magazines about various coatings that could be applied. > Toby, Jason, and all, I know of a local (to Portland, OR) shop that does "ceramic barrier coating". They only cost that I remember for exhaust systems was $10/ft. Not only does this make your exhaust pretty and durable, but it keeps the heat inside and out of your engine compartment, and the higher exhaust heat supposedly flows better (faster?). They also do a "ceramic dispersion" coating, basicly a flat black ceramic to facilitate the release of heat (good for the case and heads?). As I remember from the literature this technology was developed by them with NASCAR racers who had their disk calipers getting so hot the brake fluid was boiling. The ceramic dipersion coating decreased the heat by 50%. If this is true, it's all wonderfull stuff. Anyways, this place is called RM Engineering. It's a little hole in the wall shop in Milwaukie, OR. The head guy is Russ Meeks. Phone: (503) 659-4278 Regards, Peter Parker
