What it can't do. You won't be using King Starboard to build boat hulls, because it's not a structural material. That means it needs to be supported by a load-bearing frame or substrate. You also won't be using King Starboard where temperatures are likely to exceed--or even get close to--180 degrees Fahrenheit, because it'll start to melt and you'll have all sorts of problems. And King Starboard expands and contracts with normal temperature variations, so you'll need to allow for that when you assemble various components. more
