Corrosion Inhibitor Selection — Quick Reference
Corrosion inhibitors protect metal surfaces, electrical connections + mechanical components from rust, oxidation, moisture damage. Selection turns on application (aerosol vs bulk), environment (indoor vs outdoor vs marine), and service life (short-term storage vs long-term).
| Product | Format | Best For |
|---|---|---|
| CorrosionX (Penetrant + Inhibitor) | 355/473ml aerosol, 473ml trigger, 3.78L liquid | Metal surfaces + electrical + marine — workshop standard |
| CorrosionX HD (Heavy Duty) | Aerosol + bulk | Demanding environments — outdoor + marine + heavy industrial |
| CorrosionX XD (Extreme) | Bulk | Severe industrial — longest service life |
| CRC Instant Protection | Aerosol | Quick rust prevention on machined parts — short-term |
| CRC Long Life Anti-Rust | Aerosol + bulk | Long-term storage + outdoor exposure |
| Inox MX6 Anti-Corrosion | Aerosol + bulk | Australian-made — UV + humidity + salt formulated |
| Lanox (Lanolin-Based) | Aerosol + bulk | Marine + electrical contacts — natural lanolin base |
| VCI (Vapour Corrosion Inhibitor) | Paper, film, capsules | Enclosed storage — vapour-active protection of stored parts |
Critical: Surface prep — clean + dry substrate. Apply thin film evenly; thick application doesn't extend life proportionally. Electrical contacts: use ONLY products labelled safe for electrical (most modern formulations are; check label). Storage rule: long-term outdoor storage = heavy-duty grade + reapply per spec. Brands: CorrosionX, CRC, Inox. Companion: lubrication, greases, penetrating oils.
Rust & Corrosion Inhibitors
Corrosion inhibitors protect metal surfaces, electrical connections, and mechanical components from rust, oxidation, and moisture damage — extending service life and reducing maintenance costs. AIMS stocks a range of inhibitors and corrosion preventatives suited to different environments and application formats, from aerosol sprays through to bulk 20 L drums.
CorrosionX
CorrosionX is a penetrating corrosion inhibitor and moisture displacer formulated to protect metal surfaces, electrical connections, and marine hardware. Available in aerosol (355 ml, 473 ml), trigger spray (473 ml), and liquid (3.78 L), as well as the heavy-duty HD aerosol for demanding environments. CorrosionX XD offers enhanced performance for severe industrial applications.
CRC
CRC Instant Protection and Long Life Anti-Rust are aerosol formats for general metal protection on stored or in-service components. CRC Soft Seal provides long-term film protection for metal surfaces going into storage. Lectra Shield is a heavy-duty electrical film formulation designed to protect switchgear, electrical panels, and connectors from moisture and corrosion. CRC Long Life Anti-Rust is also available in a 20 L drum for bulk applications.
Rocol, Molytec, Pacer & WD-40
Rocol Moistureguard and Rustshield are corrosion preventative sprays available in boxed quantities of 12, suited to depot stock and site kits. Molytec Soft Cote is a light universal metal protector in aerosol. Pacer S81 fish oil rust inhibitor and S80 cavity rust inhibitor suit automotive, agricultural, and marine cavity applications. WD-40 Specialist Rust Prevention Lanolin lubricant is suited to outdoor and marine hardware.

People Also Ask — Corrosion Inhibitor Products
Q: What's the difference between a corrosion inhibitor and a lubricant?
Corrosion inhibitors form a protective film on metal surfaces that prevents oxidation — they're designed for storage protection, surface preservation, and corrosion prevention rather than reducing friction. Lubricants reduce friction between moving parts. Some products do both (Inox MX-3, WD-40 Specialist Long-Term Corrosion Inhibitor) — combining storage protection with light lubrication. Match the product to the primary need.
Q: How long does corrosion inhibitor coating last?
Depends entirely on the product and the environmental exposure. Light spray-on inhibitors (Inox, WD-40) protect for weeks to months in light exposure. Heavy-duty preservation inhibitors (CRC Long-Term Corrosion Inhibitor, Tectyl-style coatings) protect for years in moderate exposure. Marine and outdoor exposure shortens protection significantly. For long-term storage, match the inhibitor's expected service life to your storage interval.
Q: Can I apply corrosion inhibitor over existing paint?
Generally yes — most spray-on corrosion inhibitors are designed to coat over existing paint, primer, and protective coatings. They form an additional barrier without bonding chemically to the substrate. For rusted areas, treat the rust first (mechanical removal or rust converter) before applying inhibitor — coating over rust just traps the corrosion underneath. For paint preservation, light inhibitor coats extend paint life in storage.
Q: Which corrosion inhibitor works best for marine environments?
Marine environments need higher-spec corrosion protection — look for products rated specifically for salt exposure (often labelled 'marine-grade' or specifying chloride resistance). CRC Marine 6-66, Lanocoat (lanolin-based), and dedicated marine corrosion inhibitors outperform general workshop products in salt-laden conditions. For boat trailer and coastal vehicle storage, apply liberally and re-apply seasonally.
Q: Are corrosion inhibitors safe on rubber, plastic, and electrical?
Standard petroleum-based inhibitors can soften some rubbers and plastics over time. Check the product label for elastomer compatibility before applying to seal areas or plastic components. For electrical connectors, dedicated electrical-safe corrosion inhibitors (often labelled 'no residue' or 'plastic-safe') avoid leaving conductive residue that could cause short circuits. WD-40 Specialist Long-Term Corrosion Inhibitor is one of the more material-compatible options.
