After reading an article in Handyman Magazine on Correctdeck, I decided to have my sundeck replaced with this product. I am so pleased with this product that I would highly recommend it. I chose the gray (they offer 4 different colors). It does show some discoloration from wet, rotting leaves but keeping it swept prevents this along with hosing it down once in a while. My dog runs and jumps around on it all the time and her nails never scratch it like on wood.
