Good product

This is a good product. I wanted the product that would deal with some wetness, so I made sure to buy the "MARINE" product (there are two types). It does work and it worked excellent in sealing an area that was hard to reach.

Works on kiddie pools

I use this on those blue plastic kiddie pools, that wind up cracking from the sun. Works well to seal small leaks and cracks. Just hold up to the sun and you can see where the holes are. I spray on the underside, be sure to clean off plastic underside, for good adhesion to plastic. Repels water and kiddie pool will last another season for my pups.
