Military grade aluminum LOL

I saw the commercial. Sounded like they were saying the tool box is empty? The steel used on bodies today is quite brittle. Saw a 2009 Silverado at a body shop the other day. Metal fatigue on the bed was significant. It was splitting in places, and splitting around several of the spot welds. The shop was replacing the front wall, as it had a split toward the center running top to bottom. No fifth wheel hitch or bed liner. No sheet metal damage to floor, sides, or rails, only worn paint from having things slid in and out. Body shop owner is going to highly recommend Rhino Lining or Line X to the owner to cushion the steel from the vibration that is some of the cause of fatigue. He states vehicles built in the last 20 to 25 years exhibit a lot of metal fatigue that virtually never occurred prior to that time.
