### ⭐⭐⭐⭐⭐ This stuff really works!
*by G***O on 13 February 2025*

I’m glad I purchase this, I needed it to paint my banisters in the front area of my home because I did not want the wood to rot. Glad I purchased this it doesn’t allow the wood to rot It turns it into like a hard plastic coat. I wish I used it in the back of my house now I have to replace the wood banister. It’s a really good waterproof paint. It’s tough to put on, so make sure you have some gloves And a sturdy paintbrush, because it goes on like glue.
