Review: No runs, drips, or errors - Worked
Review: Perfect solution to bathroom - There was a gap between bathroom tub and floor tiles that was concerning for moisture. The nice thing about this product is you don't have to be a handy man to use it. I had to cut the tip a few times to get the desired amount out. It did require some strength to get it out then I just gently blended it into the gap. It dries clear which I love. It's also waterproof. I would recommend wearing gloves as I was overzealous and forgot. It's really hard to get it off your hands. WEAR GLOVES!!! Maybe manufacture could put in a small tool to help blend it in. Other than that it was just what I needed. I should have read about how to store it after use as this purchase may end up being a one time use if it dries out. I would definitely but it again if need be.
