Pickup Truck Bedliners Used to Protect Pentagon

Technology that's been around for more than a decade is now being used in the war on terrorism.

It's not computer software, or an electronic device, but a simple substance you find on a pickup truck. It's a thick, black spray, made out of polyeurothane -- a fancy name for liquid plastic. It dries in seconds, and creates a protective armor so strong that the military believes it can save lives in an explosion.
