How Rust Protection Works
Rust is the result of the corrosion of iron and steel. Iron is produced from iron ore. Iron is created by heating iron ore, and steel is produced by combining iron ore, carbon and other selected metal alloys. Iron has a tendency to return to its natural form of iron oxide or rust.
To understand how rust is created, consider the chemical reaction in a battery:
A carbon rod (called the
cathode) is surrounded by a zinc case called the
anode. When a wire is connected to the outside of the battery through the two terminals, current flows between two metals through an
electrolyte (electricity conducting paste). Not only does current flow from the zinc case to the carbon pole, but particles of zinc are eaten away (corroded) and deposited on the carbon pole, through molecular movement. A similar occurrence happens on your car's metal surfaces. Miniature "batteries" are formed all over by:
- Two different metals near or touching one another (Eg. seam welds).
- Impurities within the metal causing localized areas of differing electrical potentials all over its surface.
Different concentrations of oxygen in metal, causing localized areas of differing electrical potentials across the surface. In order for these "batteries" to operate they must have an electrolyte. Water is a suitable electrolyte - even humid air will work. If the moisture contains acids (usually from air pollution or salt from the ocean or road) the electrolyte conducts electricity very efficiently, speeding the corrosion process. An automobile is exposed to these conditions through:
- Humid or Salt Laden Air.
- Rain and snow.
- Condensation.
- Pockets of dirt that hold moisture from the rain or snow.
Rust-Gard uses a microprocessor controlled circuit to generate a negative electrical charge to your car's grounded body panels which in turn inhibits the forming of rust. Unlike conventional rust-proofing that is sprayed onto the underbody of your car,
Rust-Gard protects all continuous metal panels throughout the car. Rust-Gard is particularly effective in reducing rust and corrosion formed when the underbody of your car receives nicks and cuts to the vehicle manufacturers own body sealant, during the course of its normal life.
Cars today has approximately 3,000 welds. Welds and their immediate vicinity are the areas most vulnerable - and are the areas hardest to protect with conventional rust-proofing treatments. Rust-Gard is the only practical method to protect all the continuous metal throughout your car, including the inner cavities.
Through innovative design, Rust-Gard works especially well in humid and harsh environments - the times when your automobile will need it most. Rust-Gard has been manufactured to reduce rust and corrosion from both the outside and inside of your car.
Electronic Rust Proofing / Rust Protection is better than chemical Rust Proofing
