The RustStop® RS-5 is a precision electronic device which incorporates concepts based on cathodic protection, that have been in daily use protecting ocean going vessels, boats, underground pipelines, offshore oil rigs, bridges and other large capital investments for over fifty years.
RustStop® RS-5 is the only automotive system available that successfully combines both Impressed Current and Sacrificial Anode technologies to make it effective in inhibiting corrosion in both wet and dry conditions. RustStop® RS-5 should not be confused with standard impressed current or sacrificial anode products, and the successful combination of the two is complex and has taken over 12 years to perfect. 

How does RustStop Stop Rust?

How does RustStop® work?
designed aluminum sacrificial anodes (rust magnets) are supplied with a unique graphite based self adhesive and are easily mounted onto  both the  front and rear of the body of the vehicle (and also body sides for the 24 volt unit) and then connected to the RustStop® electronic unit mounted near the battery in the engine compartment.
By outputting a positive charge of approximately 38 to 43 volts onto the anodes, the negatively charged Free Electrons are attracted toward the anodes and away from the body of the vehicle.  So instead of the vehicle rusting, the RustStop® anodes now do the corroding.
