This product is fantastic for outdoor sealing work. I used it to secure a trellis last year on concrete with no screws. Im using it now on gutter repairs

Great grab feature.
This is fantastic to grab and hold items. Leave for 24hrs or more then see how strong this is. Black colour suited my needs.

Useless underwater
Despite claims to work underwater, once this stuff gets wet it won't stick to anything. So whilst it may well cure underwater, unless the items to be repaired have been stuck together in the dry, it won't work.
