      No luck

      I have two leaks that are only drips. I used this twice just like the directions said and so far nothing has changed. I will probably try it again. I'm not saying this is no good, it just does not work for me.

      Great Product- Works Incredible

      I was skeptical that the product would work but I decided to try it. I had a leak in my hut tub, maybe at a union or valve. Service shops were not interested as finding this type of leak could take time. I used the leak sealer as indicated twice, 48 hours apart, just to be sure. It has been three weeks since the last application and I do not see any evidence of the leak, and the tub has maintained its water level. Thank you! You saved me some serious cash.
