The media could not be loaded. BIGGEST PROBLEM IS UNCLOGGING THE PUMP! SEE VIDEO FOR MY EXPERIENCE. I've installed the Flat Out in two of my UTV tires. I haven't used it long enough to say how well it works. But I can say putting it in the tires was difficult. The first tire was smooth and simple and only took a few minutes. Halfway through the second tire, the pump became seriously clogged. SEE ATTACHED VIDEO. It took the better part of an hour to unclog the pump. I discovered that it didn't have a check ball in the valve as per the instructions. Instead, there was a small, plastic, one-way valve. I almost lost it in the product. But the valve wasn't the problem. The clog occurred in the 90 degree angle of the pump. I HOPE THE PRODUCT PLUGS TIRES AS WELL AS IT DID THE PUMP!!! I finally got the plug cleared using a wire and air nozzle. After clearing the clog, putting the pump back together with the small plastic, one-way valve, the process went smoothly. I'll follow up after using the product about leak protection. PS: It was a mess taking apart the pump with all the product inside, but cleanup went well with just water. That was nice.

I have used this product for the past year. It DOES work better that SLIME! Glad I used it.

My lawn tractor tires live on. A couple of slow leaks have been repaired instead of replaced.

OK, I bought this for my dad who is a farmer and his tractor tire has been leaking air for 10 years. He has taken it to different shops to try to get it repaired with no luck just would constantly put air in it every few days with the air compressor parked right next to the tractor so I bought this for a present for him after watching our review on YouTube about it and boy was he happy and couldn’t believe that it worked. He doesn’t have to put any air in at all whatsoever now also uses it on the four wheelers side-by-side three wheelers and lawn mowers Lives in Ohio, where the weather is hard and cold winters so the stuff is proven you’ll be super happy you got it. Life will be much better with it.

I wrote to Multi Seal an email with the following question, regarding the difference between FlatOut and Multi Seal HD 2500: What is the reason you don't use the 3/4" sealing capability on all your formulas? Is there a downside to it?Multi Seal replied: "Depending on the formula depends on the amount and sizes of the fibers used which determines the size of puncture the formula will seal. Our flat out does up to 1/2" , which generally works well for personal (retail) customers. Or we have our commercial line that we have a formula for ballast filled tires which does up to 1/2" our Pro HD 2500 does up to 3/4" and our Armor 3500 does up to 1 3/4". As far as why we don't use the 3/4" on all formulas some customers do not need punctures sealed that large so we have a range of formulas for different needs.They are not all the same, it is going to depend on what application you need product for will determine which formula is best for your situation."This answer is not especially satisfying. Why wouldn't a customer want added sealing capacity? I could give an explanation, but it would be a guess.

worked great....

I have a large zero turn mower that is 10 years old and had a slow leak in the front tire. I tried fix a flat but even a full can would barely get any of the product into the tire and would end up oozing around the valve. After a long search, I found FlatOut. I was reluctant at first because it required removing the valve core, which I had never done. (I'm a 60+ year old female.) But the ratings were so high and the fact it was made with Kevlar, changed my mind. And I am so glad!! The instructions were so simple, core valve came right out (and the tool and new core valve is included), the tube that you pull from the bottle, fit snuggly on the valve stem yet was not difficult to put on. I elevated the bottle, added the amount I thought it needed, removed the tube, pushed it back in the bottle, replaced the cap, and then put the new valve stem back in. It only took a few minutes. And no mess! I had put on rubber gloves, expecting some to spill but it's a thick liquid and does not seep out anywhere it's not supposed to! I filled the tire with air and checked it each day for a week to make sure there was no leak before I used it. I then mowed some rough ground that is hilly and rocky and when I was done, the tire was perfect. I was so pleased I did the same thing to the other tire that never lost any air because I didn't want to wait for a leak.BUY THIS PRODUCT if you are tired of messing with slow leaks or flat tires! I will never use anything else. I purchased a package of core valves and taped them on the bottle so I'll have them when needed! I would give this product 10 stars if I could. It states on the bottle this product was used in the military, so it really has been tested. Thank you FlatOut for a product that actually does what it says!

I bought this for my fat tire E bike that I had gotten two flats on in the two months that I’ve had it. I ride it around my property on mowed trails and stuff there’s Mesquite here and there, I put almost half a gallon into each inner tube. I even use some plastic armor inserts. Well, I got another flat! A long sharp thorn went in the side of the tire into the inner tube and all the air came out. I filled it back up, leaked out again 10 minutes later.I’m really surprised because I was very excited about all the good reviews about it. Turns out I probably should've used Slime. I wish I could find a solid foam tire for my 20’ x 4’ fat tire.
