COUPLER TEC CouplerTec Rust Prevention 4WD System
The 4WD System has been specifically designed to protect the Four Wheel Drive or SUV vehicle from rust, even when these vehicles are exposed to *OCCASIONAL use within highly corrosive environments such as; driving on salted roads or beaches. (*1 day per month, alternatively, up to two weeks per year). This product is best suited to vehicles that are in reasonably good condition e.g. NO existing rust. (For older vehicles or vehicles with minor rust problems, use the larger 4WD Heavy Duty System or 4WD Extreme Heavy Duty System.)
CouplerTec's Patented Capacitive Coupling Technology interferes with the electrical charge between Iron and Oxygen so it becomes hard for these elements to combine to form rust. In other words, the technology interferes with the metal's ability to react with Oxygen.
CouplerTec's Capacitive Coupling Technology achieves this by creating a negative (-) electrostatic surface charge on the metal surface of the protected structure. The (-) Oxygen atom is repelled by the (-) electrostatic surface charge.
