Works like it should!
I’m using this to try and reseal an air bag for one of my baggers on a rat rod. Had a large leak in one and very slight leak in another. The slight leak seems to hold but I’m experimenting with the large leak. Trying to keep filling and let it set for a cple of months then fill it again before I attempt to add air. I’ll post an update. But for small leaks it seems to work well.

Gemplers super tire sealant.
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.

Don’t waste your money
I thought it was very impressive to see the bulletproof sealer but I had no idea that it probably meant mosquito military because the smallest gun I have seen is a bb gun which would probably fail to shoot through a bike tire and if it did this stuff wouldn’t even seal the hole, it looks like to me its just the same sealer they sell at wal-mart except a little different food coloring was added to the product and make look slightly different but jacked up the price to $80 a gallon, it’s ridiculously high for the job it does Next time just go to wal-mart and get it from there so you don’t have to wait for it a few days to arrive just to find out it’s not working
