Some of this claim I would be suspect of. The materials used on road vehicles send to be a lot of 5xxx and 6xxx series alloys, and have quite different coating requirements of the 2xxx series seen heavily in aircraft. A wrap is no substitute for an epoxy prime and topcoat when it comes to corrosion, at least on the salt spray testing I have seen.
