Review: Decent product, as good as seen on TV. - Bought for waterproofing layer on a garden waterfall feature on top of the liner. Have tried several of the other flex seal products, the spray was quick and easy, the caulk worked decently as well for making a fillet and sealing cracks, but this? This was awesome, would definitely recommend in my situation. Brushed on with a 2 inch brush, layed out flat as it dried. Great build up, and one coat is really all it needed. If you're sealing a water feature, or basin for outdoor use, this works good. Just let it cure before you let any livestock/animals near it just to avoid making them sick.
Review: Covers well - This stuff works well I coated a door with mine.
