Wheel Arch Rust Protection That Lasts – Stop Rust Before It Starts

Rust on your car’s wheel arches is more than just an eyesore—it can cause MOT failures, weaken the structure, and lead to costly repairs. Whether it’s a rust hole on the sill near your wheel arch or surface bubbling on the arch lip, corrosion spreads fast.

Lanoguard provides a powerful barrier against moisture and salt—the main culprits behind wheel arch rust. With one easy application, you can protect your arches from the inside out and stop rust dead in its tracks.

Common Rust Issues Around Wheel Arches

Wheel arches are notorious rust hotspots, especially in the UK’s damp climate and salty winter roads. Here's what you're up against:

  • Surface Rust that creeps up around the inner lip of the arch.
  • Rust Holes on Sills Near Wheel Arches, particularly where water collects.
  • Paint bubbling and cracking, a classic sign of corrosion under the surface.
  • MOT failures due to compromised structural integrity around the arch or sill.

 These problems are not just cosmetic. Left untreated, rust
can spread quickly, weakening the vehicle’s structure and affecting safety.

How Lanoguard Stops Wheel Arch Rust

Lanoguard offers powerful under wheel arch protection and a long-term solution to stop wheel arches rusting:

  • Creeps and Seals: It seeps into seams, gaps and under surface rust, creating a watertight seal.
  • Repels Moisture and Salts: Forms a non-cracking, non-drying barrier that actively pushes out oxygen and water.
  • Self-Healing: If knocked or scraped, it reflows and reseals – no need to recoat every few months.
  • No Paint Needed: Unlike a paint-based wheel arch rust repair kit, Lanoguard doesn't trap moisture or crack.

How to Apply Lanoguard to Your Wheel Arches

Applying Lanoguard is straightforward, mess-free and can be done at home:

  1. Clean the Area: Jet wash or brush off mud, salt, and flaking rust. Dry thoroughly.
  2. Remove Loose Rust Wire brush the area or use rust removal pads.
  3. Apply Lanoguard: Spray the Moto Spray into the wheel arch cavity, around lips, inside seams and over the sill.
  4. Let it Cure:
  • Day 0: Feels oily
  • Day 3: Soft finish
  • Day 7–10: Fully cured with a satin look, soft like a candle

Avoid driving for the first 24 hours to ensure the curing process starts correctly.

Repairing Rust Damage Before Protecting

If you're dealing with deeper damage like a rust hole near the wheel arch or sill, we recommend:

  • Using a rust repair kit to patch small holes
  • Applying Lanoguard once patched, to seal and prevent spread
  • Consulting a professional for major structural repairs before protection

Wheel Arch Rust Protection FAQs

Yes. Lanoguard doesn’t convert rust, but it seeps underneath it, locking out air and moisture to stop further spread. It’s ideal for protecting and preserving areas that are already corroding.

No – it leaves the rust visible while still stopping it. That means your MOT tester can see what’s underneath, while you benefit from ongoing protection.

Lanoguard typically lasts a full season — about 12 months — with a single application. We recommend topping up yearly, coat on old coat building deeper protection.

For new galvanised sections, wait 2 years or let them weather naturally before applying Lanoguard. Otherwise, its protective qualities may interfere with the galvanising’s natural oxidation process.

If done at a garage, repairs can be costly. With Lanoguard, you can arrest rust early and avoid costly welding or replacements.

Wheel arch rust doesn’t need to be a worry. Whether you’ve just spotted the first signs or you’re looking to future-proof your vehicle, Lanoguard gives you the power to take control — quickly, easily and with total confidence.

Thousands of vehicle owners trust Lanoguard to keep their arches, sills and underbodies safe from corrosion. Now it’s your turn.

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.
