The sad truth about rust is that once it starts to form on your vehicle, it never stops—this is why preventative protection is key. But not all rust-preventative coatings are the equal. Undercoating in a Can is unlike any other corrosion protectant on the market today. Solvent-based waxes are primarily used in industrial situations, but the convenient aerosol-based packaging of this coating makes it perfect for automotive use, too. This product is what is considered “rust encapsulating,” as it can be applied to existing rust areas and deter “rust cancer.” The paraffin content of the film provides exceptional adhesion to metal surfaces, creating a barrier that prevents oxygen and water from coming into contact with the metal surface. To truly protect the undercarriage of your vehicle from the detrimental spread of rust and corrosion, use undercoating (in a can).
