Flatout Kevlar Bicycle Flat Tire Sealer and Tube Repair, 1 Gallon

*** FlatOut - The Best at Preventing Flat Tires! *** FlatOut is a one-time tire additive that prevents flats due to punctures up to ½” and stops slow leaks around the bead or valve stem or due to the natural porosity of the tire. It is made up of synthetic TangleTek fibers including Kevlar and unique DamRight fillers suspended in our special Never-Settle base fluid (non-adhesive, non-toxic and freeze resistant). When a puncture occurs, escaping air forces FlatOut into the wound creating an air-tight fiber jam. Think beaver dam but with the fibers and fillers forming an amazingly durable plug! And it’s proven, having been used in military and industrial applications for decades.
