    Honestly I think we all wish you would try it and let us know. Since mine often sits on my garage workbench for 6mos + and works fine, my guess yours will be fine. Too bad the car wasn’t driven as the agitation likely would be beneficial.

  2. I have year old sealant in my bikes, and it seals fine, I dont think this would be any different.

    If it’s still liquid it should be good. The only thing that makes it not work is if it dries out.

  4. To you and everyone that uses sealant. Orange in particular. With these huge bottles that sit still the grit medium cakes hard on the bottom. I pull a few of these bottles from the shelf weekly at work and unless you slam the bottle on the ground the grit stays caked at the bottom. Seen junior mechanics just pour the latex out without any of the good stuff in suspension.

    I have been using this stuff in my bikes for years but lately it’s been clogging my presta valves so much that I keep replacing the cores.
    Also: didn’t answer the question

  6. If it’s been frozen I wouldn’t trust it. Otherwise yeah. I’m running it.

    Sealant is relatively cheap. I’m pretty sure dealing with failed tubeless on the side of a trail is one of the circles of hell.

  7. I had a weird experience with orange seal a couple of years ago. Set my road bike up tubeless and that’s what I had for the mtb at the time so I stuck some in each wheel. The tyres were a pain to get on, and I don’t tend to change road tyres like I do mtb tyres, so that sealant ended up in there for at least 2 years. One day I decided to check them as I expected it would be all dried out, but what I found in each wheel was a clear oily liquid? Completely transparent, no signs of dried sealant or any grit. Only time I’ve ever seen that with sealant.

    It should be fine, but first you should shake the bottle like a baby that won’t stop crying.

    If the particulate will still integrate with a shake, it should be good. If the particulate stays clumped at the bottom, it’s probably not good.
