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.
I've never had any issues with the Help section elbows and @ $4, they can't be beat. They look exactly the same as OEM to me......down to the color of the o-rings.
There are differneces in the Help section ones, and thus the problem. Not sure if it's visual, but the chinese ones won't last...according to the Bonne guys.
Now I am curious...whats the difference?
