When I used it on mine, I moved it so the leak was at the bottom of the tire and left it sit for a few minutes instead of just getting on and driving around. I just thought it would seal it quicker/better.

 

Don't know how many gallons of this tire seal we used over the years. Almost every new machine out of the crate got at least a couple big pumps from the 6 gallon can. Made for tractors and industrial use,but was great at stopping medium size punctures from giant thorns we have down here. Couldn't use too much or handling was squirrely at high speeds.TRC6 Texas Refinery Tire Sealant - 6 Gal Container
