The "Teflon" thing is nothing more than a polymer wax. If you want a high-quality polymer wax, go with Zaino Brothers... <$75 will get you a kit that will have all you need to apply your own barrier, and the stuff is awesome (I easily go year or more between coats, and bird poop and sun-fried egg (don't ask) wipes off or rolls off in the rain).

The rust prevention thing is complete crap (take it from an electrical engineer with a partial background in (among many other things) materials). Rust is a chemical reaction between iron and oxygen (and is sped up by an electrolyte, such as water and road "salts"), creating a new substance. There is nothing you can hook up to the battery that will prevent such a reaction. The manufacturers of such devices are confusing rust with galvanic reactions, which depletes one of the materials via ion migration.
