Having tried to plug my back tyre yesterday after a naughty sharp stone pushed through it, this is just a reminder that puncture kits with their little packet of 3 mushrooms and glue seem to have a shelf life.
My mushrooms were off and my glue was hard. But i got there in the end, having used 3 not very mushy mushrooms and two tubes of hard glue.
Maybe get a new kit every couple of years :Wow:
Don’t you get the mushrooms that are individually sealed a bit like tablets?
I could have told you the glue went hard though 
The sealing foil on my packet of mushrooms was perforated . It had been rattling around under my seat for years… :crazy:
Ahh right that explains it lol.
The sticky string style kits are better in my opinion .
yup, ordered some of these. 
Does the sticky string have a shelf life?
will let you know in a couple of years when i am stuck on a motorway hard shoulder somewhere in the rain. Honestly, I expect so but not sure.
Think it`s shelf life is as long as a piece of string.
The aerosol sealant/inflaters have quite a short shelf life too. The last time I used one (on the car) it was definitely “iffy” when only about a year old.
Sealed well enough but that was one soggy tyre for the 4 or 5 miles to the services to put on the spare wheel.
my sticky string is 4 years old and still sticky … Always make sure you have a pair of gloves for handling it . Effective but horrible .
The stringy stuff and the aerosols are only good for small holes. I had a bolt go through my rear tyre, leaving me with a round flap of a hole about 9 or 10 mm in diameter. I had to get home. The stringy stuff wouldn’t hold it, but rubber plugs and glue managed to seal it to get me home and then on to Essential Rubber for a new tyre (which had not a lot if tread left anyway).
Strange the string did not work ? We us sticky string to fix dump trucks tyres with rebar holes punched in them . Just keep stuffing more strings in . thats the reason we have th string is it does work on big holes.
NumNum
What are your thoughts on the spray in stuff?
I have never got the spray in stuff to work on its own . Only way I got it to work was screw a self tapper into the hole then use the spray … But all it did was supply air the screw was doing the work … And that was on a quad bike so low pressures anyway .
I was doing this at Sparky’s house. He’s quite a well known stunter who swears by the string, but the string just kept pushing out. Maybe the carcass of the tyre (Pirelli Diablo) was too thin for such a big hole.
Could have been the problem …I can see the spring in thy rubber helping on a thin carcass that has no spring of its own … Do what ya gotta do . You got going … Its all good )))
