Check dumpsters behind appliance stores or warehouses that sell big freezers and refrigerators. I found a 4x8 ft 2 inch thick piece when I checked a dumpster while picking up a new dryer.
Yeah, I guess I could paint it white. But I started thinking, maybe I can just make a double layer and fill in the crack with some white caulk or something.
