Review: Essential repair material for your toolbox. - I love this stuff. Hardens like a rock. Allows me to fix pot metal chairs and weathervanes without brazing. Easy to apply and mold to shape. Sets up in an hour, but soft and pliable to work with. Not a race to the finish, like some materials. Epoxy putty, gorilla glue, and some duct tape goes a long way for some red green fixes without too much skill, knowledge, or danger (like using a welder). Recommend.
Review: Works underwater - This stuff did work to patch a small underwater tear in our above pool liner(Intex). It worked well for awhile, but it did eventually start to work off though and come loose slightly where water would slowly leak out again. We do have lots of kids that come over and get pretty crazy in the pool though, so I think maybe if I patched it from both sides of the liner it may have held. I only applied it on the inside underwater and that’s why maybe little feet kept hitting it and loosing it. I would give it another shot and spend more time next time patching on both sides and I think that might have done the trick. Summer is almost over though so this will be a task for next year when there’s no water in it.
