How to Prevent Rust and Corrosion on 4WDs and Trailers

Rust does not happen overnight. It builds quietly until the damage is too late to ignore. Whether it is a 4WD, boat trailer, work trailer or caravan, Australian conditions are harsh. Salt air, beach sand, mud, red dust, humidity and rain all work together to attack exposed metal.

The good news is that rust prevention does not need to be difficult or expensive. The key is creating a protective barrier before corrosion starts and then maintaining it.

Why standard sprays do not last

Petroleum based sprays evaporate, wash off and dry out surfaces. This is why they need constant reapplication. As soon as the coating disappears, moisture and salt return to the metal.

Lanolin based protection works differently.
Products like LANOTEC MGX Marine Grade and LANOTEC GPX General Purpose create a long lasting, self healing barrier that:

Blocks moisture and oxygen from reaching metal
Will not evaporate or wash away
Stays flexible in heat, salt and weather
Creeps into seams, hinges and tight areas

High risk areas to protect

These locations rust first. Protecting them early saves thousands in repairs later.

Tow hitch and safety chain
Suspension and springs
Wheel arches and underbody
Winches and recovery points
Electrical plugs and connectors
Roller brackets and skids on trailers

Step by step quick routine

Clean first. Remove salt, mud and grime.
Tip: LANOTEC Citra Force cleans fast without damaging surfaces.
Apply LANOTEC. Spray MGX for anything exposed to salt or marine conditions. Spray GPX for land based applications.
Let it creep. No wiping required.
Reapply as needed. You will not need to apply anywhere near as often as petroleum sprays.

Which LANOTEC product should you choose?

LANOTEC MGX Marine Grade is the best choice for trailers, beach driving and anything exposed to salt water or coastal environments.
LANOTEC GPX General Purpose is ideal for 4WDs, caravans, work trailers, farm equipment and heavy use around the shed.

The bottom line

Rust prevention is not complicated. It is consistency. A quick application of lanolin every few months protects your gear from expensive damage and keeps it looking newer for longer.
