I took my tires to the dealer, who has them filled by a tire shop that has the equipment to do this. Apparently, it isn't a real easy thing to do, as it is a 2 part mixture that cures after it's mixed. I'd bet your dealer or others in your area would know, and if not, check out arnco's web site.
It's great stuff, though! The tire reacts just like there is air in it, but doesn't matter what you do to your tires, no flats! /forums/images/graemlins/cool.gif
