A VERY TOUGH EPOXY at the best price I could find

This is the TOUGHEST epoxy I've ever found. After it's cured, you can literally hit it with a hammer and it won't crack, unlike many other epoxies. In my experience, it takes 24 hours to fully cure, but if you need a "thickened" epoxy, which Gougeon Brothers / West System also makes (G-Flex 655), you can just wait about 45 minutes after mixing before you apply it. This avoids having to keep both G-Flex 650 and G-Flex 655 on hand. This is the glue we always wished for as kids after we broke something.

As expected from West Systems, works well and not in huge dispensers. one note of caution - keep the inside caps seperated for re-use later and don't mix them up!
