    Just broke the bead on my tires for the first time since going tubeless in early April. To be fair, this is my 1st time trying tubeless, Id avoided it due to concerns about it being a mess to swap tires... I also didnt get (that I could see anyway) any punctures to really test it out, but then Ive never gotten many flats anyway, part of why I never saw the need to go tubeless. My rear tire had a film of latex (I guess its latex?) but did still have liquid, maybe an ounce or so. The front lacked any film, and only had maybe half an ounce of watery orange liquid... thats probably on me. Interestingly enough, I noticed the rear losing air more so than the front, but that could be due to my narrower rear tire and the higher PSI I keep it at. Either way, both tires stayed rideable for at least a week between top-offs. Cleaning the dried film out of my rear tire was pretty quick & painless, other than right on the beads it peeled off in huge sheets. So while I cant vouch for its puncture sealing abilities, it does a good job of keeping tires airtight otherwise, and seems like the 6+ month lifespan is right on. Which is what I was more concerned about anyway, personally... I didnt want dismount, clean, and reseal tires to be something I did a couple times a season. I killed what was left of my original 8oz bottle on this use, and have a 2nd on the way so I can add a little more and have some on hand. While I never really had major issues with tubes, this stuff is convenient enough that I had no thoughts of going back.

    It was really easy to clean this out of tires, making tire replacement really easy. The sealend works amazing and lasts long aswell

    This is what Ive used on the Great Divide Mountain Bike Route and never had a flat. I guess another sealant could have worked but I know this one did work. It tests well in reviews and I trust it.

    This sealant is useless. Send it back to the orange julius store. Figured I would try it since it is a little cheaper than Stans but back to Stans it is.

    It is a good sealant on road bike wheels. I was using stans on MTB for years without any problem. When the tubeless trends on roadies I add stans as well but it seems not good at all. Then I purchased this orange sealant and the flat problem never stopped me again. I will recommend this one.

    Great product, not a leak one.

    Ive been running this sealant with my Mavic Comete tubless setup since the begenning of the season. Ive had several small punctures that have sealed almost instantly with virtually no pressure loss as well as a larger (thumb tack size) puncture. The larger puncture sealed fully within about a minute of fast riding while losing about 20 PSI. This was right before a rain storm and I was glad to be able to keep going rather than stop and change a flat during a downpour.

    When I worked at a shop we used this stuff on everything. We had a lot more issues with Stans. I personally always put this in my tires. I can get this stuff to set up on non tubeless tires.
