Tubeless Glue that doesn't dry up

Punctures are a pretty rare occurrence nowadays, but one of the downsides I’ve found is that when you do have one, the glue that has been lying in the bottom of your camelback for 9 months has gone solid. Anyone found a glue that doesn’t dry up after a few months?

What do you mean by tubeless glue? Sealant? Or the vulcanising rubber stuff used to stick patches onto tubes?

Isnt it just superglue?

I have no idea what tubeless glue is either.

Yes, the glue that comes in the tubeless repair kits. I have had both super glue and more conventional stuff and both dry up after the tube has been opened the first time.

Tubeless tyre repair glue?

Ah, vulcanising solution. Just buy it in small tubes and always keep an unopened one in your pack? The anchovies will probably work without it anyway if what you’ve got has dried up.

Yes, that’s probably the best solution, thanks.
