3M 5200 fast cure
Anyone know what the shelf life is after opening the small tube? The bigger gun tube needs to be used fairly soon in my experience. Great stuff.

As JSP mentioned, store it in a freezer. I have all my sealant stored in my "bait" freeze, some as old as 5 yrs. Never a problem unscrewing the cap. Might have to prick the tip with a nail but then it'll flow after squeezing the tube.
