I actually have a bunch of unopened sugru and recently needed to repair my macbook charger. I ended up using electrical tape because the sugru packets are huge and I couldn't think of anything to do with the rest of it after repairing the charger. I guess that didn't matter so much if it's expiring anyway, but I also didn't want to leave it for 24 hours to cure.
