They mainly do race engine parts. Jeff gave a show and tell talk to our EAA chapter. On the Lancair IV, do not coat parts prior to the turbines, as it will increase the exhaust temperature in the turbines to too high a level. I coated the cross over exhaust pipe and the pipes from the turbines. The coating is on the inside as well as the outside of the pipes. It ran $10 to $15 per foot 7 years ago. Obviously, do not coat parts inside a heater. On an acroduster, the pilot reports that after flying, by the time he gets the cowling off, he can touch the exhaust pipes without getting burned. The aluminum-ceramic coating insulates the pipes and the heat goes out with the exhaust. Pipes last up to 5000 hours. I will get a telephone number for Jeff today from my hangar, if you are interested.
