Well the money is already spent! And he does not get a cut, he was telling me about a helicopter with high oil temps, those engines run at 100% all the time, so they are under a lot of heat stress, so he used Microlon it is a metal treatment one time use. He also has used it in several aircraft and feels like it works. Now that I have an oil temp gauge I guess I will find out. I need to get a good idea how the temps run now!
