I have half of the decking around my cabin in Rhino deck. It does stain and needs cleaning every 6 months or so. In one area the ends of two board warped. But, I tried to purchase more for my back deck. So, you can see I'm not totally dissatisfied with the product. Unfortunately, the dealers listed on their web page no longer deal with Master Mark Plastics. I think they keep them listed even though one said they no haven't bought materials for 7 years, just to look like they have dealers. In fact, there is not one single dealer in California. That alone tells you something is wrong with this company.
