Here you’ll find clear, factual answers about how our electronic rust protection system works, what it can and can’t do, and how it fits alongside traditional coatings. These answers are designed to help you understand the technology and choose the right protection for your vehicle or equipment.
If you can’t find what you’re looking for, please contact us — we’re happy to help.
1. What is Electronic Rust Protection?
Electronic rust protection helps slow the corrosion process that occurs when metal reacts with moisture and oxygen. The CAT System delivers a very low-level electrical charge to the metal body of your vehicle. This charge helps reduce the rate at which rust forms on painted metal surfaces exposed to harsh environments.
2. How does the CAT System work?
The CAT System uses advanced electronic technology to help protect painted metal panels from corrosion. When correctly installed, the unit emits a consistent electrical potential that spreads across the vehicle’s bodywork, helping to reduce the electro-chemical reaction that causes rust to begin.
3. Does it replace traditional rustproofing?
No. The CAT System is designed to complement physical coatings such as underbody sealants, cavity waxes and paint protection—not replace them. Together, these methods provide the most complete protection available.
4. Is the CAT System suitable for all vehicles?
Yes. The CAT System can be installed on most modern vehicles, including passenger cars, 4WDs, utes, trucks, caravans, and heavy machinery. It operates safely alongside existing vehicle electronics.
5. Does the system protect unpainted or already rusty areas?
Electronic rust protection works best on painted, intact surfaces. It cannot repair existing corrosion or protect areas where bare metal is directly exposed. For vehicles with existing rust, we recommend mechanical treatment and repainting before installation.
6. Will it affect my vehicle’s electrical or computer systems?
No. The CAT System runs on extremely low current and has no negative impact on sensors, computers, batteries, or electrical accessories. It operates independently and safely.
7. Does the system need servicing or maintenance?
Once installed, the CAT System requires no routine maintenance. It runs continuously whenever the battery is connected and draws minimal current, so it won’t drain your battery.
8. Can it be fitted to a new vehicle?
Yes. Installing the CAT System on a new vehicle provides early, long-term protection before corrosion can start—especially valuable for vehicles used near coastal areas or in humid climates.
9. How long does the CAT System last?
Each unit is designed to last for the lifetime of the vehicle. With correct installation and normal use, no further attention is required.
10. Does it stop rust completely?
No system can completely prevent corrosion. The CAT System is designed to help reduce the rate at which rust develops on painted metal surfaces. For best results, combine it with quality coatings, regular washing, and good maintenance practices.
11. Is the CAT System environmentally friendly?
Yes. It contains no hazardous materials and uses no chemicals or sprays. It provides long-term protection without producing waste or emissions.
12. Where can I buy or have the system installed?
You can purchase CAT Systems online and install them yourself — each kit includes full instructions, and free Australia-wide shipping is available.
Order directly from our CAT Systems Online Store.
If you’d prefer professional installation, you can visit one of our CAT Systems Stockists and Installers across Australia.
All stockists receive product training and ongoing support to ensure consistent quality and service.
Important Notice
The CAT Electronic Rust Protection System is intended to help reduce corrosion on painted metal surfaces when used as directed. It should not be represented as stopping or reversing rust, preventing electrolysis, increasing resale value, or protecting the entire vehicle.
