Has anyone used this stuff to seal flanges and stuff looks like a great product, but not sure if its o2 sensor safe?

Norbs, It looks interesting. My only concern would be if the squeeze out inside the header port might break off and damage a turbine wheel. Other than that it should work good. Try it and let us all know. Might be as expensive as gold though. What do they use on the Space Shuttles heat tiles? That might be the best stuff to use. Come to think of it .........the best adhesive known to man is the stuff they use on those little stickers they use on tomatoes..........I've never been able to remove one without tearing the skin off the dang tomato!
