Picked this up to glue back pieces of my saw blade guard on my Bosch mitre saw. Was skeptical, but it looked interesting. After "glueing" the pieces back together using the UV light, I was amazed at how strong the bond was. The parts are only 1/8" in thickness, so not much surface area, but I tried to bend/break the bond with a bit of force, and it felt like it was new. Time will tell...
