Rust prevention has gradually evolved over the past 40 years. In the 1970s, technicians would drill holes into individual body panels to spray oil-based chemicals. In 1983, Canadian Auto Preservation pioneered the ‘no-holes-drilled’ process that did not compromise the integrity of the vehicle body.
Next came the adaptation of a 100-year-old technology called Cathodic Protection to the automotive industry. While cathodic theory is sound, its application to automobiles was flawed due to the absence of an electrolyte. As a result, many cathodic rust protection devices were pulled from the market by government bodies, including the FTC in the USA and the Federal Competition Bureau in Canada.
In the past 15 years, a patented technology called Electromagnetic Protection has emerged that works in the alternating current (or AC) realm, unlike the DC realm used in Cathodic Protection. It emits a low power, low amperage radio frequency (RF) signal that produces a surface current covering the entire vehicle’s sheet metal surfaces, both inside and out. It is a much more effective and greener alternative to traditional spray methods. Having proven its efficacy to government through continuous testing, research and fieldwork, this technology has become the preferred rust protection system among proud vehicle owners and new car dealers worldwide.
