stoopid question re: silicone seal cure/drying time

[SDGuy]

thanks guys - I'm going to guess the stuff is too dated - I know the tube was at least two, possibly three years old.

So - time to scrape it off and start over.
I know - 1st world problem...not overly upset, was just trying to finish this small project with what's on hand and avoid a trip to a store.
