This seems to work very well. I will say that it seems to be pretty important to move the wheel around as soon as you can to distribute the product within the tire. I was held up for a few minutes and the Liqui tube seemed to start to set up in one spot and made the tire out of balance so I had to work quick to get it to distribute to the other parts of the tire. It seems to have worked though and so far the tires are holding air very well. I will be interested to see if it lasts for a long time but so far so good.
