Cool stuff
Bought a Swisher rough cut mower to pull behind the Yamaha Rhino to cut our 6 acre field. We were cutting down 8 foot trees, no problem, but one tree had big thorns on it and destroyed the rear tires of the Rhino. Replaced all tires, and since we still have to mow the field I opted for adding this to the tires. Very easy to use, and now I have the confidence that if we get a puncture we will still have air. Also bought their flat fix kit that comes with CO2 cartridges. Brilliant space saving idea! So, haven't had to test this stuff yet, but I'm fairly confident it will work. An added bonus is that it can clean up with water. I've heard stories of tire places not wanting to touch a tire with the other brand that comes in an aerosol can, as it's dangerous and messy. Time will hopefully not tell. It's like insurance - hate to pay for it until you need it, but hope you never do.

Got me home after a sidewall cut!
I am very happy I bought this tire repair kit earlier this year. I was out riding my UTV today and had a flat tire caused by a sidewall cut. I used the tireject kit and was up and running again pretty quickly and it was more than enough to get me back the the truck and trailer. I bought this kit instead of going with a spare tire. I have already bought more of the fluid to replace what I used today.

Amazing sealant and easy to use even in cold weather.
This product is amazing. It poured right into my tire even though it was -8 celcius. It sealed the crack in my aluminum rim and the the leaky tire bead after I hit a rock. Sealed everything and got me back to trailer and it is still holding air.
