This wasn't the first time my spa had a leak but after seeing a mechanic rip my insulation to find the leak and $$$$ I tried to repair this work yourself the next. I checked how bad the leak was and used a water absorber to catch the leaking water. The picture is one. I decided it wouldn't hurt to try this product before you start tearing things up. I set a dry pan down to soak up the water as the other was soaked. To my great surprise and delight, the leak was sealed. The area was dry. I know some of the reviews aren't great, but maybe this works for small leaks, not big ones. Glad mine got fixed. I will keep following. Update: Unfortunately, it looks like the leak is bigger than I was hoping for. About a week later it started dripping again. Gave him another dose of the product but it didn't work. Again, probably great for small cracks/leaks. Mine seems a lot bigger.
