The device detects the amount of electricity necessary to create an electrostatic field that will charge the vehicle’s metal structure with ions and then keep those ions from mobilizing, which is what causes corrosion. By maintaining that electrostatic charge between the oxygen in the air and the car’s metal, rust is held at bay and your car stays shiny and new looking.

I invented a similar device that makes me have erections like when I was 18. Works like a champ.
