Does anyone here have direct experience using the spray polyurea coatings for ponds? Curious what your experiences have been. Stuff looks way too good to be true, so in classic pessimist style I'm actively looking for cautionary tales. I'm not interested in experiences with the epoxy-style "Pond Armor"/"Pond Guard" and similar products, only the polyurea ones, especially if you have had it for a few years.
