Slime Tubeless Tire Sealant, 1 Gallon

used various brands of spray can type tire inflator sealers many times. They are portable and convenient but are only a temporary fix at best and sometimes don't work very well. The liquid slime tire sealer is a completely different product. It isn't a pressurized inflator for emergencies. It requires the use of a tool to remove the valve stem core, to install the thick liquid sealer into the tire. A cheap plastic tool was included but it broke the first time I tried to use it. However, I also purchased the slime brand valve core removal tool and it is a relatively easy procedure. It requires some time and effort and it is a little messy but it is a very effective and lasting fix for leaking tires. I have a John Deere riding lawnmower that is over 25 years old. Although the original tires still have most of their tread, they had developed slow leaks that have gotten worse over time. I put slime in all 4 tires and once they had sealed, they remained inflated. The slime isn't cheap but it was quicker and more cost effective than replacing the tires. Do yourself a favor and buy a real valve stem core removal tool, the cheap plastic tool included with the slime is too weak.
