I use this every now and again but I don't have an immediate use for it. Does it expire?

Silicon/caulk stuff tends to expire, so no garrantees after that it will work but it matters less if its not job site related, good to have on hand.

Yes, it does. I've had silicon fail to cure due to expiration. You'll get a few years unopened however.
