    Tubeless sealant failure

    I am running Stan's goo in my tubeless setup for about 4 months now. I know it eventually dries up and you need to re-fill. Does the sealant fail catastrophically or does it just start loosing air more?

    Going to Kingdom trails in a few weeks and want to be prepared.

    On my ghetto converted tubeless setup with DIY sealant, it just has a higher risk of burping.

    If you're on UST rims and tires, they should be airtight without sealant, but the sealant makes a perfect seal and will stop punctures.

    They'll still hold air but wont seal punctures.

    Sometimes the latex will clump up, leaving a big ball and clear liquid. Thus the sealant becomes useless.

    The Stans does tend to clump up and dry after a while, making formations that look like they came off a coral reef. It will by no means be a catastrophic failure, however you will be more likely to start losing air a bit more quickly.
