Review: Fountain Fix - This sealant was purchased to repair a hole in my outdoor fountain / worked well / would purchase again
Review: This is awesome stuff! Recommended! - I had a difficult problem. I bought a rainspout adapter which diverts water outside of the aluminum downspout into a water barrel. Problem was that it is made of rubber, flat, and up against an aluminum and wavey shaped downspout. Of course it leaked like crazy. If only I could find some way to seal this to stop the leaking. This stuff did the trick. It is white, and a very thick consistency. Formed a perfect seal and in addition holds very strong. It sticks to everything including your hands so be careful. Bought another tube for just in case. Unused product will stay usable in the tube for a while, but for longer term, you may want to place it into another very air-tight container. Highly recommended.
