## Customer Reviews

### ⭐⭐⭐⭐ works but a bit expensive
*by G***P on February 5, 2025*

It shrinks somewhat so a second application may be needed to fill in valley. Applying excess is needed to deal with shrinkage, but over and under doing it is all too easy. Very durable stuff, it would outlast your teak.

### ⭐ It was hard as a rock
*by A***. on March 2, 2025*

It was hard as a rock

### ⭐ Horrible product
*by J***Y on December 20, 2023*

The product was impossible to dispense. It was practically dry and I threw it away. I will never purchase this product again. There is a local marine store, I will pay more but at least they will stand behind what they sell.
