Has anyone ever used this or had any experience with it? It is supposedly a unit that protects your paint and body on your car from rust and corrosion. RODE means "Reduces Oxidation Destructive Electronically) and it is supposed to run off any 12 V system. Says that a DC voltage is pulsated through all metal surfaces on your car and it forms a field fluids of ions....
Was just wondering about it and I am pretty sure it's a pretty old unit. (10 years old maybe)?

Thanks!
