Any of the sugru experts on here know if out of date sugru still works OK? Expired in January.

I know of the Surgu Dam in Turkey…not sure if it can go out of date anytime soon though. 😉

Not an expert but doesn’t it last 18 months if you keep in the fridge, as against 6 months at room temp?

Only one way to find out for sure (assuming you mean Sugru)!

Depends how cool it has been
I have some in a cool garage that worked fine several months after expiry date.
I think they have extended the shelf life.
They now say and maybe originally did that you should keep it in the fridge
