The MSDS doesn't declare a shelf life. I've kept tubes around for quite some time, but am eventually suspicious of any glue's ability to adhere if stored too long. Storing in a refrigerator, I would think it would keep a very long time.

I used JBW to repair the broken hinge ear (prev owner) on my gas lid. At least I had the spring and broken piece. It's still working today.

Hey, test your glue by mixing some together. If it hardens, it'll work. I stick a toothpick in it, or some such. If it doesn't harden, you can try a little more hardener, but it's likely toast by then. It's cheap; get some more. I just used some on something less than a month ago, and I bought that stuff probably 3 years ago. It's probably good for 5.

In the tube or out? I've had mine for over a year and it still is good. As long as you keep the caps screwed on it'll last a long time.
