FlatOut Sportsman Formula Tire Sealant — 32 oz

FlatOut Sportsman Formula is a Kevlar-fiber tire sealant that prevents flats and seals tread punctures up to 1/2 inch. One 32-ounce bottle treats a tire and keeps sealing for 10+ years — it washes out with plain water and never turns into a sticky mess. Riders in the fat-tire and off-road forums prefer it over Slime for big tires. Price is for one 32 oz bottle.
