Product Description
The 4WD Heavy Duty system has been speciï¬cally designed to protect the Four Wheel Drive or SUV vehicle from rust, even when these vehicles are exposed to *FREQUENT use within highly corrosive environments such as driving on salted roads or beaches. This system may also beneï¬t older 4WD vehicles that are suffering from minor existing rust problems. But remember, as good as this product is, it is not a miracle cure for badly rusted vehicles, as the more rust a vehicle has, the harder it is to stop.
