Where I am in California (desert), I don't see many really rusty vehicles. But take a magnet and try it on some really rusty iron you may have around where you are. Also, a magnet will not stick well to a vehicle that has a thick enough layer of Bondo, so you can try the magnet on anything you know that has Bondo, to prove it for yourself. Then try it on the "rust free" truck. Having to drive that far to check it out is kind of a pain, but that choice is yours. HTH
