Review on 🔴 FlatOut Tire Sealant Sportsman Formula - Prevent Flat Tires, Seal Leaks, with Valve Core Tool, 32-Ounce Bottle, 1-Pack, RED by Chad Cypert

I have used a bottle of this on my 2 e bikes. Unfortunately I was a day late when I realized that one of the tires was flat and had a good sized stud. So I patched the tube, put FlatOut in all the tires and pumped it up. After 3 weeks I noticed again that one of my tires was flat. I searched and found another Doozy off the top. I pulled it out, pumped the tire back up and spun it around a few times to smudge the FlatOut a bit. 6 weeks later and this tire is still holding air. This stuff does everything they say it does. I'm a happy customer. It's much cheaper than tire covers and will seal a puncture that even tire covers can't prevent. Very important.
