### ⭐⭐⭐⭐⭐ After 3 years...!
*by W***D on December 23, 2024*

Bought this 3 years ago and coated the bottom of my boat in fresh water, pulled the boat out recently and nearly 5% growth of algae and quaga mussels. With so many ablative products out there, it's tough to decide. This stuff worked more than expected, will be purchasing again as I am VERY satisfied with it's performance!
