  • Comments - This has lots of grey long fibres in what is probably an ammonia solution - slightly irritating to skin The key thing NOT mentioned is that it is for schrader car type valves. If you have those, there is a valve core remover and a tube to fit over the valve so you would hope minimal spillage. If you use narrow presta valves you need a separate core removers . And will then need to pack the tube of the valve to get a rough fit ( teflon tape) You will then find that the gunk easily blocks a narrow presta valve tube so use small amounts and work outside as grey goop everywhere. There are recommended amounts but no gradations on the bottle so you will need to decant and measure. Does it seal well. - no idea as yet but after a series of autumn punctures on the e-bike with stiff tyres and heavy you do not want to be doing inner tube changes on a cold wet track It certainly seals presta valves. My concerns are. A) how much actually went in and b) it is very viscous so will it reach a puncture in time and c) will it clog the valve core when inflating On balance would suggest slime if presta. If schrader, this offers higher levels of protection. Oh and a 27.5” tyre needs 150ml so this is for robust e-bikes not anything weight sensitive.
