We tested Finish Line Tubeless Tire Sealant for some time before we offered it on the web site. Seems there are so many sealants and we had not been able to identify one brand that stood out from the rest and we did not want to add anything to the site that was redundant. After using Finish Line Tubeless Tire Sealant for a few months we have added it to the site because it stands out as the best in class.
Claims about it not drying out and lasting the life of the tire appear to be true and we have had some very good results with it sealing up flats.
Finish Line Tubeless Tire Sealant is our number one recommend for road, cross and MTB tubeless tires.
