This stuff is Fantastic. I have a riding lawn mower and one of the front tires, which is small, had been running low for a couple of years, we took it off. to fill it with the liquiTube and you could see cracks all around the outside of the tire. The liquid tube oozed out of one of the cracks and sealed , immediately. My brother rolled the tire around real good before we put it back on the track lawn mower. It has been 3 days now and today I mowed for 1 1/2 hrs and the tire as full as it was the day we put in the LiquiTube. This stuff is fantastic, it really, really works!

Hard to install as instructed.

Size: 32 oz

Nearly impossible to get it in the tire through the valve. Yes I removed the valve core. Broke the bead on the tire and dumped it in. That worked great! So far no leaks. They should definitely redesign the installation method.
