“Decent sealant; have run it for years in multiple bikes and never really had any issues in any of the tubes I've run. Only time I've had flats with this sealant have been from things that I wouldn't reasonably expect any sealant to address (bad pinch flats, gashes from broken glass, things of that nature. Had a couple of nasty holes that required *eventual* patching but the sealant kept that from being a 'come back to a flat tyre at the end of the day' event into a slow loss of pressure noticable over the course of a couple days.”
