I used this sealing product around my pipes and vent outside . The previous sealant had cracked and ants were getting inside. It was very easy to use and wasn't messy at all. I had some left over so I put the package into a ziploc bag. It did a great job for me and the price was very reasonable.

I love this stuff, used it to block a hole under the bathroom sink around the pipe. Great price, fast shipping and incredible stuff!

I read the reviews of the product before buying, like someone said buy the 5lb package. I'm glad I did as I already used about half a pound to seal all the gaps around the kitchen plumping pipes. Started using surgical gloves but they were no match for stickiness of the product. Applied using bare hands and clean up was easier than using plumber's putty. Excellent product, pliable right out of the package - easy to shape and apply. Elated with this purchase and would recommend for any DIY-er. Time will tell how it holds up but for now I am very satisfied.
