Larry, That is exactly how the Ford dealership in my town went away. Its been twenty years or so and everybody got out. I wish I had my camera with me when I saw it. All the new cars in the showroom were toast. and every car in the service department as well. It was an old building with HUGE wood beams and all wood construction from back in the day. At the new dealership there was an impact wrench framed on the wall that was melted flat. Might have even been the culprit tool.
