## Customer Reviews

### ⭐⭐⭐⭐⭐ Works perfectly!
*by K***N on July 3, 2025*

Flex Seal allowed me to fix the galvanized tubs that we use for drinks. It sealed any of the openings that have happened throughout our use. Now I can continue to use them without any leaking.The directions on the canister are super easy to use. The product dried to the touch in like 20 minutes and then was dry for use within 24 hours.I didn't notice a smell while using it. Also know that the caulk is white, so you may have to paint over it.

### ⭐⭐⭐⭐⭐ Great to use in RV
*by A***H on July 14, 2025*

Easy to use and no calking gun required. I re-calked my RV shower and had about 1/2 a tube left - which I saved. I like the ease of use, the ability to adjust the flow size and ease of cleaning up. It soft set quickly and it fully cured within about 24-hours. Results look nice and waterproof.Very handy stuff for home or RV.Great value and will buy again as needed.
