Go to Amazon and search for "mesh tarp". I LOVE these things! I first used one as a sunblock for my paddleboard that sits in the sun. I just lay it on the board and tie the corners down (also keeps the board from going airborne in a storm) It blocks most of the sunlight, yet lets the board "breathe" so it doesn't get covered in mildew. I also use one as a sunshade, tied off to posts on my deck; another one (tan in color) serves as a beach blanket; and I just ordered a small one to protect my kayak when it's in the bed of my truck (the bedliner seems rather rough in texture).
