This system has been specifically designed to protect Motor Cars* (*hatchbacks, sedans, wagons, SUV’s and small vans**) from rust. It will also dramatically reduce the effects of corrosion on those vehicles which are frequently exposed to use within highly corrosive environments such as’ driving on salted roads. In other words, it will extend the life of these vehicles. (**For large Vans (Long Wheel Base) use the larger CT4 Heavy Duty System).
