Review: A great way to finish off project that is Wood - Are utilize this on a project with cedar wood and it worked absolutely wonderful. I have also used the non-water-based satin finish. I like this one better because I can save my brush by Mary rinsing it out and it does work better than the urethane that is not water paste Because that one goes on pretty thick and if you put it on too thick it wrinkles. This water-based comes off, looking cloudy white when you brush it on, however dries perfectly clear like a mirror. I do suggest using this as it’s much easier to use and never goes on too thick.

### ⭐⭐⭐⭐⭐ An excellent polyurethane
*by A***R on June 20, 2025*

Why did you pick this product vs others?: This is my go-to polyurethane when I use it for coating a project. I apply it with a foam brush and I find it better to apply and better than other polyurethanes (Varethane or plain Minwax polyurethane versions).
