to repair a few of them, but could never find glue that would work with them. there still are a few damaged ones around and if you have any ideas on how to fix them, let me known, and i will see if it works. the reason i kept the damaged ones is that the 4-inch lid opening makes them easy to fill from a stream. there is a stream across from my house and i figured they would be useful to carry dirty water to my garden.
here you can see the crack at the bottom of the threads. always check this area when you go to buy a can.
