Why rust-proof a vehicle?

Metal is a large and important component of vehicles. Unfortunately, though, there’s a downside to it. When it combines with air and moisture, it starts to rust. This, as we know all too well, is quite common because vehicles are more or less constantly exposed to corrosive agents. The stronger the effect of corrosive agents, the more rapid the process of oxidation. Sea, airborne salts (sea vicinity) and winter road salting/sanding are highly corrosive. However, such innocent activities as car washing can also trigger the onset of rust.
CouplerTec electronic rust-proofing systems, on the other hand, interfere with the process of oxidation and, by tricking it, prevent rust from taking hold.
