King StarBoard XL is a lightweight, quality marine-grade high-density cellular polyethylene sheet, up to 30% lighter than the original King StarBoard. King StarBoard XL has a matte finish on both sides of the sheet. It is environmentally stabilized to withstand the harshest outdoor conditions. King StarBoard XL does not rust, delaminate, or rot when exposed to UV rays, moisture, or water. It is ideal for a wide range of marine applications, from boat components to equipment mounts, and looks good enough for use in high-visibility applications where structural strength and edge finishing are not important. For maximum versatility, standard colors are made to coordinate with the original King StarBoard. The polymer sheet never needs to be painted or refinished, works like wood, and is easy to fabricate with standard woodworking tools and techniques.
