Underwater Sealer

I have used this product a few times now - we are plagued by foxes trying to get the fish and digging their claws in the butyl lining.
It works well; I find you get the best results if you keep the area to be fixed dry. I know you are supposed to be able to use it under water but this doesn't always work.
Unfortunately it only seems to last a couple of years then the repair has to be done again.
