Donbryce,

Florida cars don't rust unless you live on the beach and drive it on or near the sand. We get so much rain that salt just can't sit on a car long enough. It's far more likely that Massachusetts road salt is to blame. We rarely see rust down here unless the car was an island dweller. Even then, it's usually the body panels and not the undercarriage for some reason, unless it's a light pickup truck and then the whole thing kinda just erodes away. Something about the bed......
