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.

I’ve tried several tire sealants over the years on my ebikes and scooters, but FlatOut QuickStrike is by far the best I’ve used. From the moment I added it to my bike tires, I noticed a difference—it’s incredibly easy to install, and you don’t have to convert to tubeless to benefit from its protection. The formula is thin and spreads quickly, sealing punctures almost instantly so you don’t lose much air.What I feel that really stands out is how effective it is. I ride my ebikes through rough terrain with lots of thorns and debris, and since using FlatOut QuickStrike, I haven’t had a single flat ( unlike before ). Even when I’ve picked up multiple punctures, the sealant has handled them all without a problem. I feel that the peace of mind it gives me is priceless, especially on long rides or commutes where a flat could ruin your day ( and It has in the past ).Another big plus is that it’s a one-time application—it won’t dry out or turn into a mess inside your tire ( like that Green Stuff ). It’s also safe for both tubes and tubeless setups, and works well in my 20 inch and 14 inch tires. I’ve used it on my ebikes and scooters and the results have been consistently impressive.Make me feel confident of the durability of my tires on my ride. I bought the gallon bottle because I have a few ebikes and scooters. this stuff works great!If you want to spend less time fixing flats and more time enjoying your ride, this is the sealant to get. Highly recommend!

Awesome product! Rode 130 miles before punching my tube plucking goat heads out if my tires every day.

The product worked as advertised. I would rate a 5 BUT the pump came apart in my hands during use. I called their customer service twice and was told twice they would send another one. Still waiting.....the product is no good without a pump

This stuff really works would buy again

The sealant is good. The gallon pump is a joke. Pump stopped working 4 pumps in. Went and got another replacement pump from automotive store, also broke after 4 pumps. Ended up cleaning out an old Slime bottle and pouring in the flat out sealant in the slime bottle, so I could actually get it in my tires.

I live in an area with a ton of mesquite trees. I put this in anything with tires and it works great. I’ve pulled out a bunch of thorns and this stuff seals the holes. I will continue buying it for my needs.

I was clearing a field full of mesquite trees, and my tractor tires were getting destroyed. Mesquite has nasty 3-inch thorns, and I was plugging tires constantly. Eventually, all four tires were flat at the start of each day. These tires had been plugged more than 10 times each.I bought FlatOut Quick Strike and followed the instructions exactly. The pump dispenses about 1 oz per pump, so I put 30 pumps in each tire, and the bottle was mostly empty by the time I finished. Typical with any pump dispenser it was also difficult to get the last bit out of the bottle using the pump.It’s been a week now. One tire has lost about 1 PSI, but the other three are still holding exactly where I set them.Considering how badly these tires were damaged, I’m impressed so far. This is the first time I’ve gone more than a day without dealing with flats in that field.
