You probably already know that epoxy is good for creating a tough, clear join between pieces of many solid materials.What surprised me is Gorilla's clever, clever dispenser which allows multiple uses of the same dispenser. What surprised me even more is that it was over TWO YEARS between my first and second use of this specific epoxy dispenser.and it still worked liked a charm. (be sure to follow the simple two-step directions before storing the dispenser)After a brief hesitation in one tube, it then dispensed as neatly as when new. The bond set up like it should, and so far it's as clear and strong as I'd expect.I've thrown away so many super-glue type adhesives after one use, because the container has dried out or sealed itself by the time I go to use it again, that I was actually taken aback. Impressive, never mind most of those two years were in my garage, which gets very hot and very cold through the course of the year.This is the way to do it-- low waste, low frustration, high effectiveness. Highly Recommended.
