Not sure if this product would do the job as described. It says it would cure under water, I don't see that posible unless you use a lot of gardener, more than equal parts.Why, well I applied it yesterday using equal parts, at about 11am, it's now past 10am the next day, it was about 60 f, sunny. Today 54f, sunny, no rain, and it's still sticky and gummy.I think they should provide a bit more gardener, like an once more. Equal parts is not doing it. I've other like in weld and other, they stay gummy for a period of time longer than specified but harden after several hours. This one has been almost 23 hours and is still to sticky, gummy and uncured. Frustrating. I have no idea, how this will cure under water, unless you use a larger amount of hardener. Equal amounts ain't doing it.
