MarathonFlat Free Tire Sealant Bottle, 32-Ounce

Works as described.

We have a wheelbarrow that gets left outside the horse stall, and of course the pneumatic tires go flat as the rubber oxidizes over several years. I tried to find Marathon no-flat solid tires as replacements, but Marathon is closed during the COVID-19 lockdown, so we opted to try this, despite the negative things I've heard about using goo to inject in a tire as a way of getting it functional again.However, I found the kit (sealant, tire valve remover, vinyl tube) to be easy to use, and my wife tells me she's happy to have her wheelbarrow working again.So far, so good!

I used about double the recommended amounts to stop pinhole leaks in 3 lawn mower tubeless tires. I was pretty meticulous about following directions and in a warm climate. Installation was uneventful but 1 of the 3 tires still leaks. The recommend quantities are not sufficient to coat the entire inside of the tire, plan to use double the recommended amount.

You will need to double up recommended amount of product

Worked fine, easy to use. I let it set in very hot water for awhile to make it easier to put into tire.

seems to work very well----only goat-heads to deal with so far

The gunk works. The problem is the tube that connects to the squeeze bottle is very stiff and in cold weather almost impossible to get over the valve stem. I'd try another brand with a good dispenser.

We had a hand truck with a air blown tires. One of the tires would leak out slowly. I used the recommended amount and I haven't had a problem with the tire since. Great job!
