Rust Check is a premier automobile body panel protectant that has been used successfully since 1973. It is a light liquid product that is applied inside body sections as a pressurized spray.
Rust Check protects metals by displacing moisture and treating the surfaces with highly effective corrosion inhibitors. The corrosion inhibitors form an adsorbed (bonded) layer on the metal surfaces. This microscopic layer acts like a series of tiny umbrellas, shielding the surfaces from water molecules. Just as a car battery will not work without its electrolyte, metal corrosion will not occur if moisture does not contact the metal.
