Rust-Gard uses a microprocessor controlled circuit to generate a negative electrical charge to the car's grounded body panels which in turn inhibits the forming of rust. Unlike conventional rust-proofing that is sprayed onto the underbody of the 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 the car receives nicks and cuts to the vehicle manufacturers own body sealant, during the course of its normal life.
Frequently Asked Questions - Rust Protection
Benefits of Electronic Rust Protection
- Rust Proofing provides higher resale value for the car. A properly cared for car with no rust will achieve a higher resale or lease-end value than a well-cared for car that exhibits signs of rust. Not even scratches will rust.
- A cleaner car. Air-borne dust will no longer be attracted to the car.
- Eliminate static shocks from the car. Suffer no more pain during dry weather.
- A better looking car. A rust-free car.
- Eliminate Static Shocks.
- In 95% of cases, static shock is completely eliminated. In those rare cases where it is not completely eliminated, it is reduced.
How Rust Protection works
Rust-Gard uses a microprocessor controlled circuit to generate a negative electrical charge to the car's grounded body panels which in turn inhibits the forming of rust.

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 the 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 localised areas of differing electrical potentials all over its surface.
Different concentrations of oxygen in metal, causing localised 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 efficiently, speeding the corrosion process. An automobile is exposed to these conditions through:
- Rain and snow.
- Humid or salt laden air.
- Pockets of dirt that hold moisture from the rain or snow.
Cars have approximately 3,000 welds. Welds and their immediate vicinity are the areas which are vulnerable and are the areas hard to protect with conventional rust-proofing treatments. Rust-Gard is a practical method to protect all the continuous metal throughout the car, including the inner cavities.
Through innovative design, Rust-Gard works especially well in humid and harsh environments, the times when automobile will need it. Rust-Gard has been manufactured to reduce rust and corrosion from both the outside and inside of the car.
Conventional rust proofing (also referred to as chemical rust proofing) consists of a physical barrier that is sprayed onto the underside of the car. The chemical used inhibits the battery effect mentioned above and therefore prevents rust. The problem is that the only parts protected are those covered by the chemical.
If, for example, there is a scratch in the paintwork of the car, it will start to rust. Also, if the chemical is removed from an area (eg. by a tree branch touching the underside of the car) the protection is removed from the area affected. Electronic rust protection protects the whole car.
Rust-Gard uses a Patent Pending method of operation called Pulsed Current design. The active principle that delivers Rust-Gard's good results is a high-frequency direct current charge to the entire automobile's metal frame work and surface. Once installed, Rust-Gard delivers this charge many times a second for a pre-determined period of time, forming a protective coating of excess electrons. It is this coating which lessens the destructive oxidation and corrosion of the car's metals.
Rust-Gard is available from duco scratch.
