There is an argument that any product using anodes cannot work unless the anodes are submerged in water or buried in soil, and so do not work on cars or any other open-air equipment. This has some truth, but read further to discover why RustStop® RS-5 is so effective on cars.
BRIEF ANSWER
RustStop® RS-5 uses a special partially conductive tape on the Rust Magnets™ which acts as a constant electrolyte ensuring conductivity and protection in wet and dry conditions.
FULL ANSWER
Basis for the argument:
Original Cathodic Protection systems, like for pipelines, had the anodes totally separated from the steel being protected. This technology relied on the soil between the anode and pipe to be conductive in order for protection to occur. The soil became the electrolyte.
It could never be used on open-air equipment because there was no way for an anode to hold a stronger charge, and still impress current to the steel. If the anode was in contact with the steel, the charge was short circuited and if it was separate is was insulated, hence zero protection.
So in order for protection to occur, the anode needs to be separate so a strong charge can be held, but have a conductive material between (electrolyte) that would allow current to pass, but not create a direct short.
Why RustStop® RS-5 is so effective:
- RustStop® RS-5 does not use classic cathodic protection.
- The secret lies in the special tape that hold the Rust Magnets™ on.
- This tape is a specially made graphite based, open-cell partially conductive tape which allows the positive 45V to be held, but still allows current to pass through. So the tape becomes a constant electrolyte, in wet and dry conditions.
- Because it is open-cell, the tape also responds to any moisture present, even atmospheric humidity and increases conductivity and protection when needed most.
