CAT Electronic Rust Protection — For Vehicles

Protects metal where coatings can’t reach.
The CAT Electronic Rust Protection System slows down corrosion inside chassis rails, seams, brackets and cavities — areas that sprays and coatings often miss. Ideal for 4WDs, caravans, utes, boats, mining and fleet vehicles exposed to salt, moisture and harsh conditions.
Key Benefits
-
Continuously suppresses rust activity while the vehicle is powered
-
Reaches internal and hidden areas where coatings cannot physically coat
-
Works alongside paint, underbody sprays and lanolin coatings to extend their lifespan
-
Low-draw system — operates silently 24/7 without affecting vehicle electronics
-
Modular design — suitable for small passenger cars through to heavy-duty off-road vehicles
Proven Performance
What CAT Can Achieve
The CAT System has been proven to reduce the rate of corrosion by disrupting electrochemical rusting processes, particularly when combined with an effective dielectric coating.
What CAT Cannot Do
CAT cannot reverse existing rust damage, as the energy required to reverse the rusting process exceeds the system’s capabilities. While CAT can slow down or halt corrosion progression, it cannot restore rusted components to their original state.

Choose your System
For passenger 2WD & 4WD vehicles that mainly drive on sealed roads, we recommend using the “2 Coupler” System. If you occasionally go off-road, we suggest the “4 Coupler” System. For those who frequently operate their vehicle near saltwater or on the beach, the “6 Coupler” System is the ideal choice. For vehicles used in high-risk environments, such as mine sites or coastal/offshore facilities, we highly recommend the “8 Coupler” System.
