I thank you for this, and also for the link within a link, which talks about mixing it up with powered latex and ethyl antifreeze. I just looked at the cost of this stuff. And went immediately to look up the cost of powdered latex. I generally don't get flats where I ride, but it's nice to be prepared.
How does one generally find the puncture, when the air is escaping the tire from elsewhere? Surely there is a method.
