The temperature inside the cab is much cooler with this $300 paint job. The metal of the roof is at least 30 degrees cooler than the metal on the hood, after an hour sitting in the sun. Do this for yourself, your pets, and the planet. The CHP, the California Highway Patrol, figured this out ages ago. Side benefit, other cars are a bit more cautious around you, they think you might be one....
