Keep Your Car Rust-Free .
Perfect for medium to larger passenger vehicles, this advanced 4 Pad CAT System protects your pride and joy from rust using smart electronic protection technology — no sprays, no coatings, just 24/7 invisible defence.
✅ WHAT IS CAT?
The CAT Electronic Anti-Corrosion System is a proven solution for preventing rust in vehicles and machinery by using advanced electronic technology to interrupt the natural rusting process.
Unlike spray coatings that wear off or need reapplication, CAT works 24/7, protecting your asset without mess or maintenance.
“Protect your investment for under 1% of the average vehicle cost.”
⚙️ HOW IT WORKS
CAT uses a precision-tuned alternating current (AC) waveform impressed onto the metal surfaces of your vehicle. This signal disrupts the electrochemical rusting process, dramatically slowing corrosion — especially in high-risk environments like coastal, off-road, or industrial areas.

6 Coupler System – Best for vehicles frequently exposed to beach driving, saltwater spray, coastal environments, or unsealed roads.

Not sure which one to choose? When in doubt, go up a level — more protection = more peace of mind.
🏗️ BEYOND VEHICLES – ENDLESS APPLICATIONS
While the CAT System is best known for protecting cars and 4WDs, it’s also widely used across a huge range of non-automotive environments. We’ve successfully installed CAT units on excavators, mining equipment, shipping containers, caravans, trailers, marine vessels, air conditioners, agricultural machinery, and even coastal infrastructure. Whether it’s exposed to salt spray, fertiliser dust, or high humidity, CAT delivers reliable, long-term corrosion protection — no matter the environment. If it’s made of metal and at risk of rusting, CAT can protect it. Have a unique application in mind? We’ve probably done it. And if not, we’ll help you make it work.
