Gempler's Bulletproof-Grade Ultraseal Tire Sealant, 1-Gallon

Product works great. I placed it in the tires on several atvs that are operated in terrain with thorns and sharp rocks. The tires previously kept getting penetrated and going flat. After adding this product, the tires self seal.

This is some good stuff. Flats no more.

Works good but a little high priced.

for the $ so far works as it should

This stuff is absolutely worthless!! Tried it on my tractor tire, put twice the amount the chart called for in. Still leaked like crazy! Took the tire apart expecting to find a huge hole in the tube. Nope 2 very small holes!! Don’t waste your money or your time with this stuff. I’d return it but I use half the bottle on this leak!🤬

This is the best tire sealant I have used. I use it in our mowers, tractors and UTV's I have a gator that is 12years old; I put this in the tire when it was new and have never had a flat.

So far the tire has not sealed. But I still may not have enough sealer in the tire.

Great stuff. Works great on tractor tires
