Scotty, I'd say 3-4 people. It's really no problem to order the stuff anyway, we use it quite a bit here.
Lee, anywhere that you use o-rings. It's really good for the coolant elbows, but anywhere you need to use it that may nick o-rings. A group of guys could buy one bottle, divide it up equally. It's good for a club to have just one, since you don't need very much at all to use.
Ah I understand...it is really good o-ring lube. It must be REALLY slick stuff. Don't let Scotty buy too much or it will wind up in his supercharger.
