### ⭐⭐⭐⭐ Easy to use
*by T***B on July 16, 2025*

Worked great. Stopped a small leak around a screw in my kayak. Very sticky and messy to apply. A tapered tip would make it easier and less messy to apply to small areas. Probably should have worn gloves when using. As it sticks to everything it touches. I only needed a small amount, and I have plenty left over.
