Worked fantastically.

My riding lawn-mower tire has had a slow leak for years. Each week I fill the tire before mowing the lawn. I was going to break down and buy a new tire, but I thought I'd try this first. It WORKED!! My tire has stayed inflated for several weeks now. It hasn't gone down at all. I'm pleased as punch.
