I have a heavy vintage desk stapler (they don't make them like that anymore) that the top cap came loose many years ago. No amount of super glue would ever keep it intact very long. I think Gorilla epoxy worked a miracle. Same thing with the plastic top of my mop handle that has the hanging hole and came unglued so it couldn't be hung to dry. I believe it's on for the life of the mop handle now :=) That's the only two critical needs I had for it at this time, and very impressed with it. It's very easy to dispense and mix with the included popsicle stick for 20 seconds and apply. There's a tight-sealing cap included so the rest of the tube should stay usable for a long time, I put it back in the plastic cover and in a ziploc bag for storage. If I had been more careful on opening the package I could have salvaged the back and instructions too LOL
