If you need a quick fix of some Stan's sealant. This handy-dandy little 2oz squeeze bottle should do the trick. Just enough for one wheel/tire or a couple of refresher refills

The milky-white Stan's liquid coats the inner casing of the tire creating a latex-like seal while the excess liquid travels around the tire while the wheel is spinning to seal any holes or punctures in the casing from the outside world. Stan's is the best and most reliable sealant offered today. It's that simple. Shake well before use.
