Stan's NoTubes Tire Sealant (Quart)

Comments:

Does what it is supposed to do like most sealants. It does need to be replaced periodiacally. They recommend 6 months but I have found it lasts about one year

Have notice a coagulated mass in two tubes after a couple of years in use.

We use Stan's Sealant in both road bike tires (with tubes) and mountain bike tires (tubeless). Here is the [...] area, punctures are just a part of life, but flats while riding do not have to be. In the last decade, we have had hundreds of punctures, usually thorns from the many [...] flora here who have them and they all seem to.But, we have had to change a tube on the road only two or three times and never in the dirt. Yeah, getting sprayed as the sealant begins to seal the puncture is not something we look forward to. Cleaning the resulting mess off the frame after we ride home is also a leat favorite chore, but it beats changing a flat.Be sure to take along your CO2 inflater. Sometimes enough pressure escapes before a seal is acheived that you will need to re-inflate to get home. And keep moving, if you can to distribute the seaalant or stop with the puncture at the bottom of the wheel to ensure sealant reaches the hole.
