  • Designed by certified engineers with over 40 years experience in electronic rust protection and electronic rust prevention.
  • RustStop® RS-5 uses a dual technology to be effective in both wet and dry conditions.
  • The Anodes (Rust Magnets™) give customers visual proof that the system is working;
  • electronic rust protection and electronic rust prevention

    Suitable for New and Used vehicles;

  • It helps protect the entire car, inside and outside, which sprays cannot do;
  • Backed by Independent test results.
  • RustStop® RS-5 even helps control formed rust from spreading via electronic rust control;
  • As spray on coatings only protect the particular area they cover, they are prone to being worn off and need to be maintained on a regular basis. Electronic rust proofing will compliment any other undercoating or spray-on type rust proofing, increasing your protection, as rust protection electronic can only improve your rust defence.

BRIEF EXPLANTATION

Rust needs free-electrons to form. The strong positive charge on the Anodes (Rust Magnets™) attract the negative free-electrons away from the vehicle and they now corrode rather than the vehicle.

HowRS5works STEEL

FULL EXPLANATION

Any steel contains millions of free-electrons which are negatively charged and move around in the metal due to positive and negative charge differences caused mainly by impurities in the steel.

HowRS5works ATTRACT s1

 

 

 

These small charge differences (normally around 1 volt) act almost like a magnet, and so the negative free-electrons are attracted toward and accumulate at the positive points.

How RS5 works RUST s

 

 

 

When these free-electrons are exposed to oxygen and moisture, a reaction occurs and they are lost from the steel. This reaction is known as oxidation or RUST.

RustStop® RS-5 outputs a positive charge onto the Anodes (Rust Magnets™), approximately 50 times greater than that between the impurity and iron atoms. The iron and impurity atoms are now effectively all negatively charged in relation to the strong positive charge on the Anodes (Rust Magnets™) and so the free-electrons are attracted toward the Anodes (Rust Magnets™).

How RS5 works OFF s1

 

 

The Anodes now corrode rather than the vehicle.
