Protect Your 4x4 from Rust, Road Salt & the Elements

How to Apply Lanoguard to Your 4x4

Protecting your 4x4 with Lanoguard is straightforward and beginner-friendly — no need to mask, remove wheels, or strip parts.

  1. Clean the Underside - Pressure wash or brush off dirt and loose rust. Let dry completely.
  2. Apply Grease to Key Components - Use Lanoguard Moto Grease on high-wear or exposed components like nuts, bolts, brackets and suspension arms.
  3. Spray Underbody and Cavities - Use Lanoguard Moto Spray to coat the entire underside. For inside box sections, use the 360 Injector Wand (included in Injector Kits) to apply a fine mist inside cavities.
  4. Let It Cure - Lanoguard sets within hours, forming a tough, water-resistant seal. You can drive soon after.
  5. Reapply Annually - Top up once a year for continuous protection.

Common Rust Areas on 4x4s

4x4s face unique rust risks due to their open chassis, off-road use, and exposure to water, mud, and salt. Key areas to protect include:

Chassis & Crossmembers – Box sections where rust starts from the inside.
Suspension & Axles – Leaf springs, brackets and bush mounts corrode quickly.
Wheel Arches & Sills – Trap moisture and grime, leading to hidden rust.
Fixings, Mounts & Bolt Heads – Easily missed, but vital to overall strength.
Exhaust & Underbody Components – Often exposed and highly vulnerable.

4x4 Rust Protection Kits | Tough, Fast & Proven in the UK FAQs

Yes! Lanoguard is ideal for 4x4s, off-roaders, and overlanders. Whether you're driving a Defender, Hilux, Jimny or any other rugged 4x4, Lanoguard provides year-round protection against rust and corrosion caused by mud, salt, water and grime.

Focus on common rust-prone areas such as:
Chassis rails and cross members
Suspension arms and mounts
Sills, wheel arches and inner wings
Fuel tank straps and brackets
Fixings, bolts and weld seams
Lanoguard seeps and creeps into seams and hard-to-reach areas, ensuring full coverage.

Lanoguard is not a rust converter, but it arrests and stops rust from progressing. It creeps underneath existing surface rust, seals it off from air and water, and prevents it from spreading. Over time, it can even push off loose oxidation and improve the appearance of older surfaces.

Lanoguard cures in stages:

Day 0: Oily finish
Day 3: Soft and waxy
Day 7–10: Fully cured, semi-satin ‘wet look’ finish, slightly soft like a candle

You can drive your 4x4 after 24 hours, but we recommend avoiding wet and muddy conditions in that first day if possible to let the curing process begin properly.

Absolutely. Lanoguard is non-perishing and safe on rubber, plastics, electrical components, and all vehicle materials. It’s also non-conductive, so it's great for under-bonnet and electrical protection too.

Lanoguard has been designed for yearly/seasonal applications. It should be topped up at least once a year to ensure continuous protection. Although due to the simple application process there’s no harm in doing an Autumn & Spring application! The product is broken down by UV, so the more it is exposed to sunlight the shorter its life span. Inside box sections or inner chassis for example, it will last longer.

The general rule of thumb is that a little Lanoguard goes a long way, 1.8L of moto spray per application. – is ample coverage for vehicles such as Land Rovers and Pick Up trucks any vehicles over this size we would recommend more than 2L. Click here to look at our range.

Preparation is very minimal - all you need to do is jet wash your vehicle removing any dirt and grime. Make sure you remove any flaking or loose bits of rust, paint or underseal. Sometimes a wire brush can be used if needed to remove flaking bits. Ensure the vehicle is dry before you apply Lanoguard – it doesn’t have to be bone dry, as Lanoguard will displace moisture to an extent, but ensure you do not apply to a dripping wet surface. See our how to apply page here.

Lanoguard is great for chassis with surface rust. It has a natural affinity to ferrous metals and will bond to the metal underneath any surface rust, it acts as a barrier by hermetically sealing to the surface keeping oxygen and water out - stopping any rust from developing further.

Yes, you most certainly can. Lanoguard works fine with almost all sprayers, compressors, and applicators. You may find that it uses slightly more product than our trigger sprayer applicators will, but you’ll still get a nice even coverage of Lanoguard which will protect well. We do have a range of sprayers and applicators available on our accessories page.

Lanoguard reaches its final state around 7 to 10 days after application. Day 0 it is “oily” day 3 “soft” and final state is dry to the touch, but you know something is there. Like a candle to feel. Maybe a little softer. It dries to a clear / transparent semi satin wet look and stays that way for some months eventually dulling a little. But always stays clear; and of course, you can jet wash it to clean it back to how it was when you put it on. It is best to not drive the vehicle for 24hours to let it get through the first part of the curing process.

Lanoguard is eco-friendly and has green non-hazardous certifications. It does not require special handling, protective clothing or disposable gloves, which all add to the carbon footprint of utilising a product that is hazardous. The primary ingredient of Lanoguard is Lanolin which is a very ecologically safe and sound base. In fact, an entire dam in New Zealand was moved down river on a base of Lanoguard marine grease which shows you how the river authority was not concerned about any toxins that would be left as a result.
