Literally five minutes into my late 7pm ride tonight and I pick up a 1 inch long huge nail size thorn in the rear back tire. I immediately pull it out and Stan's and pressurized air burst out everywhere. I jump back on the bike and begin to ride in the mud and as quickly as I can tire and the tire seals! Stan's is the absolute greatest tire sealant you can buy worth every penny. Another great all right with a little bit of mud tonight since it rained yesterday. About 70° and a couple of trees down on the trail mostly hero dirt. Great ride - beats changing a tire inner tube! Tubeless with Stan's Rocks.
