How long will MULTI-SEAL tire sealant last?
For the life of the tire. MULTI-SEAL is non-reactive. In other words, it will not react with the tire rubber and does not polymerize, vulcanize or cure. Additionally MULTI-SEAL will not separate. In fact, at our corporate headquarters, we have a sample of MULTI-SEAL that was removed from an over-the-road truck after the sealant had accumulated over 300,000 total miles — the life of three tires on the same tube! It is still fully functional and could be used today!!!
