Pacer Rust Prevention & Corrosion Control — Quick Reference
Pacer = Australian automotive corrosion control range — fish oil rust inhibitor, cavity wax and underbody sound deadener, supplied through the panel, smash repair and automotive trade.
| Pacer Product | Format | Best For |
|---|---|---|
| S81 Deodorised Rust Inhibitor Fish Oil | 1L liquid | Penetrating rust treatment — cavities, chassis, hardware |
| S80 Cavity Rust Inhibitor | 400g aerosol | Box-section & cavity rustproofing — sills, chassis rails |
| S77 Sound Deadener | 1L liquid | Underbody sound deadening / coating |
Note: Fish oil rust inhibitors are naturally penetrating but can carry an odour — Pacer S81 is deodorised specifically to make it practical for indoor workshop use. Brand: Pacer. Companion: corrosion inhibitors, rust treatments & undercoats, penetrating lubricants, CRC, WD-40.
Pacer Corrosion Control for Australian Workshops
Pacer is a well-established Australian brand in the automotive corrosion control space, best known for its fish oil–based rust inhibitor. AIMS Industrial stocks the core Pacer range used by panel and smash repair shops, fleet workshops and trade customers dealing with rust-prone vehicles and equipment: a penetrating fish oil rust inhibitor, a cavity rustproofing aerosol, and an underbody sound deadener.
Pacer S81 Deodorised Rust Inhibitor Fish Oil
Fish oil has long been used as a penetrating rust inhibitor because of how effectively it creeps into seams, cavities and threaded hardware, displacing moisture and leaving a protective film behind. Pacer S81 is the deodorised version — it keeps that penetrating performance without the strong smell raw fish oil is known for, which matters if it's being applied in a workshop rather than outdoors. It's commonly used on chassis components, door and cavity interiors, and hardware exposed to road salt, moisture and general corrosion.
Pacer S80 Cavity Rust Inhibitor
Supplied as a 400g aerosol for controlled application into box sections, sills, chassis rails and other enclosed cavities where rust starts from the inside out. Cavity rustproofing is a standard part of vehicle corrosion protection and rust repair work, sealing the internal surfaces that a topcoat or underbody spray can't reach.
Pacer S77 Sound Deadener
An underbody coating used to reduce road noise and vibration transfer through the floor pan and wheel arches, typically applied alongside corrosion protection work as part of a full underbody treatment.
Where Pacer fits in a corrosion control program
Cavity wax and fish oil treatments handle the internal, hard-to-reach surfaces; a broader underbody or chassis coating protects the external surfaces; sound deadener addresses noise. Used together, they cover the areas most exposed to road salt, moisture and stone damage. For general-purpose penetrating lubricants and anti-corrosion sprays outside the automotive-specific Pacer range, see our corrosion inhibitors collection, including CRC and Rocol lines.

People Also Ask — Pacer
Q: What is fish oil rust inhibitor and how does it work?
Fish oil rust inhibitor is a penetrating oil-based treatment that creeps into seams, cavities and threaded hardware, displacing moisture and leaving a protective film that slows corrosion. Pacer S81 is the deodorised version, giving the same penetrating protection without the strong odour of untreated fish oil.
Q: What's the difference between cavity wax and underbody rust protection?
Cavity wax, like Pacer S80, is designed to be sprayed inside enclosed box sections and cavities (sills, chassis rails) where rust starts from the inside out and a topcoat can't reach. Underbody rust protection coats the external, visible underside surfaces. Comprehensive corrosion protection typically uses both.
Q: Why is Pacer S81 described as deodorised?
Raw fish oil rust inhibitors carry a strong, persistent smell. Pacer S81 is deodorised specifically so it can be used in an enclosed workshop environment without the odour issues of untreated fish oil, while keeping the same penetrating rust protection.
Q: Does Pacer S77 sound deadener also protect against rust?
S77 is primarily a sound deadening / noise reduction coating for the underbody, applied alongside rather than instead of a dedicated rust inhibitor like S80 or S81 as part of a full underbody treatment.
Q: Who typically uses the Pacer range?
Panel and smash repair shops, fleet and workshop maintenance teams, and trade customers working on rust-prone vehicles, chassis components and equipment exposed to road salt and moisture.
