Hydrophobic Paint
Automobile finish waxes protect the vehicle by creating a hydrophobic coating that causes water (and some oils) to bead up and roll off, thus not allowing dirt or grime or bug tar or road salt from adhering in the first place. The problem is that waxes don't last and don't cover the very areas that are most prone to rust. What I suggest is using a hydrophobic/oleophobic paint or lacquer on all painted parts of a vehicle that would offer permanent corrosion protection, and keep the car finish looking new longer- decades, even. Some car manufacturer will do this, eventually. It might be wise to be the first.

AndyL The corrosion protection on metal is not due completely to the paint used on the exterior. The metal needs to be conversion coated, that is, the metal surface needs to be treated with a zinc phosphate coating (about 1000 nanometers thick). Once painted, the zinc phosphate conversion coating (also known as metal prep) helps prevent the spread of corrosion once it starts. A hydrophobic clearcoat, color coat or topcoat will not provide that much corrosion inhibition and would not be worth the $$$. Andy L.

William L Perhaps the beast approach would be a super hydroscopic powdercoat: google "Electrodeposition fabrication of Co-based superhydrophobic powder coatings in non-aqueous electrolyte."
