I have a circle top window off a great room. When I put it in, I purchased a high-density compressed styrofoam trim that matches. Over time, the white on this trim is coming off, so I masked off all the window, and a small area around it on my vinyl siding. Spraying this on protects this trim piece and brings back the white, all in one application. I did spray it 3 times. The first to put a base, the second hits all spots missed and the 3rd is the keeper. Looks great again, and is protected from the elements.
