The advanced technology delivers complete protection without the mess or hassle of traditional sprays, so your car continues to look and perform like new.
What is a wireless Diamond Kote Corrosion Protection Unit and how does it work?
A wireless electronic Diamond Kote CPU is a device that attaches to your vehicle to prevent rust from forming. Unlike sprays or undercoating, the unit emits a controlled electrical current across your metal surfaces. This process slows down oxidation known to cause rust, without drilling any holes or a cleaning up a messy coating every 6 months.
The wireless unit installs discreetly under your hood, connecting to your vehicle’s OBDii Port. The electrical current continuously protects your vehicle from the inside out. Your Diamond Kote CPU provides peace of mind in knowing the structural integrity and safety of your vehicle is safeguarded by the most advanced corrosion technology available. At Goldwing in Ottawa, our fleet vehicles have been equipped with a Diamond Kote CPU, since 2016.
Why choose wireless rust protection over sprays or undercoatings?
The answer is simple. Traditionally we’ve relied on rust protection sprays and undercoatings. These require regular reapplications and usually end up missing those harder to reach spots, if they’re even done right. That’s a problem, because it leaves your vehicle vulnerable. There are many reasons drivers choose a wireless corrosion protection system,
- No drilling or cutting – leaving your factory finish untouched.
- Complete coverage – completely covers hard to reach areas, often missed by sprays, like seams or inner panels.
- Eco-friendly solution – sustainability matters, your Diamond Kote CPU uses no harmful chemicals or overspray.
- No more seasonal applications – long lasting protection without the need for repeated appointments or additional costs.
The low maintenance, high tech solution is the reason modern drivers prefer a wireless system.

Frequently Asked Questions,
How does the Diamond Kote Corrosion Protection Unit work?
The Diamond Kote Wireless CPU uses an advanced electronic pulse system to prevent rust on your vehicle’s metal surfaces. It works by sending a low-voltage electrical current through the metal, to disrupt the electrochemical process that causes corrosion. Unlike sprays that only protect coated areas and need annual or seasonal reapplication, the Diamond Kote CPU offers continuous, 24/7 protection for exposed and hidden metal surfaces.
Will a Diamond Kote unit void my vehicle’s warranty?
No, the Diamond Kote Wireless CPU does not void a manufacturer’s warranty. The passive electronic system does not interfere with your vehicle’s electronics or performance. In fact, a Diamond Kote CPU comes with a corrosion protection warranty, providing an extra coverage beyond what your manufacturer offers.
How long does a Diamond Kote CPU last, does it require maintenance?
The Diamond Kote CPU is engineered for long term, maintenance free performance. Once installed, the unit works for years without any reapplications or service visits. Unlike traditional undercoatings that need seasonal touch-ups, an electronic system provides consistent protection for as long as the unit is active. Typically, customers install them when their vehicle is new to get the most value.
