    This Product totally works, just make sure you use a few coats and don't just load it on all at once or only use 1 coat. USE A FEW GOOD COATS and it will seal the leak. I purchased a pre-formed pond that had a crack & it looked like they tried to seal before but still had slight leakage. I removed all previous glues & just sprayed a few coats of this flex seal and the pond no longer leaks at all, completely sealed it up.

    Works just as advertised. I used it to seal a large/long area in the bow of my 14' aluminum boat. It was easy to apply and doesn't take long to set up and cure. I'd recommend it!
