We have an island in the kitchen and the top is made of beautiful, thick walnut. Its so nice, we don't want to use it, nor did the previous owners for 15 years. I was going to make a cutting board to place on top of it of either walnut, ash, white oak or oak to be able to use it. The wifey does not want it covered up. So maybe that leaves some sort of clear plastic. The question is what kind of plastic (probably 1/4 - 3/8" thick) can we set a hot pan on and cut on it also without damaging the plastic? Know there's lots of different kinds of plastic out there. Were looking at approx 27"x32". Thanks. Randy
