Rust doesn’t always start where you’re looking. For many vehicles, the real damage begins underneath: exposed frames, suspension parts, cavities, wheel wells and the under-tray. Our undercarriage rust-proofing service provides a robust barrier between the elements and your vehicle’s vulnerable underside.
Undercarriage rust proofing is a protective treatment applied to the underside of your vehicle, the part most exposed to water, road salt, mud, and debris. Over time, these elements can eat away at the metal, leading to corrosion that weakens the vehicle’s frame and key structural components.
Unlike traditional paint, rust-proofing coatings penetrate seams, joints, and hard-to-reach areas most vulnerable to corrosion. Once applied, the coating forms a flexible, long-lasting layer that won’t crack, peel, or flake off even under constant vibration and exposure to the elements.
This service is especially valuable for vehicles frequently driven on rough roads, near the coast, or off-road. Whether a daily commuter, 4WD, or commercial work vehicle, under-carriage rust proofing adds an invisible line of defence that helps extend its life and keep it looking and performing like new.
Laser cleaning makes rust removal simple, safe, and effective. It restores metal surfaces without the mess or risk of traditional methods. Here’s why it’s such a wise choice:
Once rust starts under the vehicle, it can quickly weaken critical components. Proactive rust proofing slows the process down significantly.
From salt-laden wet roads to weekend off-road drives, the underside of a vehicle takes a beating. A dedicated coating helps defend against moisture, salt and debris.
Corrosion on chassis and underbody parts isn’t just cosmetic — it affects safety and resale value.
With proper preparation and application, under carriage rust proofing offers extended protection with minimal upkeep.
We follow a careful, step-by-step approach to make sure every surface gets the attention it needs.
Inspections help to assess the condition, existing rust or damage, and access needed for treatment.
Cleaning, degreasing, and freeing from dirt, salt, or debris is essential because the coating only works when it bonds properly.
Brake lines, exhaust components or sensors are areas that should be protected before the whole process.
It is necessary to apply a specialised under-body protective material to all critical areas, including frame rails, suspension arms, wheel wells, floor pans, and cavities.
After the coating cures, the underbody is inspected for uniform coverage and access points. We also show you any areas to monitor in the future.
Don’t wait for visible rust to do the damage. With expert undercarriage rust proofing from Melb Extreme Coatings in Melbourne, you can strengthen your vehicle’s core, safeguard it from corrosion, and confidently drive.

Longevity depends on conditions and usage, but high-quality under-body protection can last many years when properly applied and maintained.
Yes — but existing rust needs to be cleaned or treated first. Coating over active rust will not be as effective.
As early as possible — ideally before any visible rust or winter/harsh conditions begin. Early treatment is always easier and more cost-effective.
