And this differs from plywood HOW? Plastic is fine but why choose plywood over solid wood?Sure, Ross. It dings. It absorbs moisture and discolors. It can be slick when wet. It decays. I would prefer an FRP with a composite synthetic wood overlay. I have varnished and loved many a wood floor, but faced with a grand for just one replacement panel... that would never match... I went for Lonseal. Natural wood is superior in texture and beauty, but you get over it. I always wanted a Choey Lee Lion. When I could afford one, I was over it. 19 years with a wood boat made me a realist.
