Given the cost of this product, I thought that it would perform far better than it has. I had a leak in a fibreglass salt water pool. The sealant worked well enough for a little less than 12 months, then went soft and powdery, with the result that the leak returned. I suspect that the chlorine in the pool may have been the cause. The other issue is actually getting the stuff out of the tube. It is quite thick in texture and takes a lot of force to get it to feed out of the tube. I am very disappointed in this product and could not recommend it for the purpose for which I bought it, but having said that, it might work OK as an underwater glue for mosaics provided there is no chlorine in the water.
