Flat Out QuickStrike Tire Sealant - Prevent Flat Tires, Seal Leaks, Contains Kevlar (1 Gallon + Tool, Small Tire/Bicycle Formula)

Great product! I was skeptical at first but when I followed the instructions it worked wonderfully! The durability is actually pretty good, I check the air and it's good after a few days and have to repump my tire because I go through a lot of small potholes and bumps along the way while I ride, value for money is a bit pricey but you get what you paid for, honestly it should be worth half the price, it works wonderfully against any leakage and the application is actually pretty simple you just got to follow the instructions, it is actually very messy so you got to be very careful but easy to clean up though, the size is perfect which should last you for awhile. The pump clogging I keep hearing about, all you have to do is rinse everything out with water because it is waterproof, to get the stuff out the pump just pump it with water and the water will clean everything out You don't need to use soap.

Make sure you attach the plastic tube extension to the pump. Has stopped flats from enormous thorns in my fat tire ebike.

I don't know why I've waisted money money on Slime, I could not get the bead to seal on the aluminum wheel that has corroded from the Slime so I thought I'd try FlatOut, 10-15 squirts in all 4 tires and a few trips around the yard and all tires are still inflated 2 days later. I'm super happy!

Pretty impressive product. Haven't actually gone over any nailes, etc, but this stuff did manage to clog the pump really good and that's ~3/16" opening that it sealed air tight. I was able to clear the clog with bailing wire and would just immediately clog again, so I have no doubt that goat heads and probably even roofing nails don't stand a chance against this stuff. Slime has let me down with goat heads before, so I'm stepping up to this stuff. On the downside, it's probably gonna clog your pump and that's a PITA, so minus 1 star for the issue with the pump. I would recommend paying extra for one of FlatOut products that doesn't require the pump.

So far so good. No flats

After not even 1 tire the pump got stuck. I completely took the pump apart and cleaned everything thinking there was a clog somewhere and it didn’t fix it. Couldn’t use it after that because you need the pump to get the product in.

This is awesome stuff! Wish I had known about this alot sooner. Just don't forget, you can pump it through car/truck tires with tpms sensors. But works fantastic on all my other tubed and tubeless tires. I even had a cart all 4 wheels were completely flat and weather checked tires, went ahead and tried it and still full and working great two months later.

Was kind of hard to pump into my lawnmower tires, used a jug split between the 4 tires. Had to jiggle and force the liquid in as it jammed up a few times on each tire. make sure you shake during filling! Works well on bouganvilla spines
