I have seen one or two threads wondering about this stuff so, having had call to use it recently I can now report on it.
For those who haven't seen it, it is a tyre sealant aimed more at tubular tyres. It is much lighter than the usual liquid sealant as it takes the form of foam once it is out of the tin. It fits very easily into your pocket although I wouldn't fancy landing on it in a crash!
So at the weekend I'm ten miles into a ride when I got that feeling you get when you know there is no air left in the rear tyre. To be fair I it is a feeling I haven't had since trying tubulars. Despite the shocking condition of the roads around here, I haven't suffered an impact puncture despite taking a couple of hits that I know would have seen off a clincher.
Once stopped with the wheel out I found the sort of flint that a master Neolithic knapper would have been impressed with stuck in the treads of the tyre.
Making sure all the remaining air was out and that the valve was free, I pressed the valve into the open end of the bottle and pushed firmly.
The tyre inflated and dribble of foam emerged from the hole vacated by the flint and then it sealed. The tyre continued to inflate right up to the time the top 'exploded' in my hand. Think of a very violent wet fart and you won't be far away. A large quantity of gick ended up on me but, despite that, the tyre was up.
You are supposed to then top up with a pump. I didn't have one so gingerly remounted and headed back home. The tyre stayed inflated at around I reckon 50/55 psi and saw me home no worries. This morning I inflated the tyre up to around 110psi and it is still fine this evening.
I will let you know if the next ride sees it off or not.
