User Rating: Slime Tire Sealant. This stuff works great. I had a lawnmower tire that had a slow leak, it sealed it and that was it. For the others that rated this product keep in mind that Slime does not inflate tires. Slime also will not seal or repair a leak in a valve stem or a puncture in a sidewall of a tire. was skeptical that Slime Tire Sealant would work for this blown out tire. Unlike Fix-A-Flat that uses a propellant in the can to push the sealant into the tire, Slime used just the pressure of squeezing the bottle by hand.
