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.
