• Oh. I am now worried. I’ve used it for a year without issue.. maybe I genuinely never had a puncture that needed sealing...

  • Don’t worry

    I have had loads of punctures that sealed and I was unaware of them.

    I got thousands of miles out of s-one tyres and it was only when I finally took them off I found the mudguards of commuto x biek were lined with dried stans sealant.
