Chassis Rust Protection That Works – The Lanoguard Way

Why Does the Chassis Rust?

Your vehicle’s chassis is its backbone, but it’s constantly under attack from moisture, grit, salt, and debris – especially here in the UK with our wet roads and gritted winters. Rust forms when iron reacts with oxygen and water, and over time it can weaken chassis rails, cross members, suspension mounts, and even vital safety points.

Even galvanised chassis can rust over time – especially once the zinc layer wears or becomes damaged. While galvanising offers great resistance, galvanised chassis should weather for around two years before applying any coatings like Lanoguard, to ensure the oxidation process isn’t disrupted

Common Rust-Prone Chassis Areas

  • Chassis rails and box sections
  • Rear crossmembers and spring mounts
  • Body mounts and outriggers
  • Inside the chassis and hollow sections
  • Tow points and suspension brackets

How Lanoguard Stops Chassis Rust

Lanoguard isn’t a paint, and it’s not a rust converter—but it is incredibly effective at arresting and sealing existing rust to stop it spreading.

Here’s how:

  • Creeps into seams and surface rust, sealing out moisture and oxygen
  • Self-healing and non-cracking, unlike rigid coatings
  • Remains flexible and clear, with a semi-satin finish
  • Repels water, salt, and chemicals – even jet wash-safe after curing
  • Bonds naturally to ferrous metals and galvanised steel (once weathered)

Treating Rust Inside the Chassis

Lanoguard’s 360 Injector Wand is designed to protects internal chassis sections, like box rails and hollow members, which are often neglected.

If you’ve got concerns about chassis rail rust repair, Lanoguard helps prevent the need for future welding by halting rust before it becomes structural.

How to Apply Lanoguard to Your Chassis

Applying Lanoguard is simple with minimal mess Here’s a quick overview:

  1. Clean the chassis – power wash and remove mud, flaky rust, or grime
  2. Dry thoroughly – water must be off the surface
  3. Apply Lanoguard Moto Spray – with our trigger sprayers
  4. Focus on seams, joints, and inside chassis rails
  5. Allow curing time:
  • Day 0: Oily feel
  • Day 3: Soft coating
  • Day 7–10: Fully cured, semi-satin and ready for the road

Note: Avoid driving the vehicle for the first 24 hours to allow it to get through the first part of the curing process.

Please visit our How To Apply. For a step-by-step guide to the prep and application of Lanoguard, with video demonstrations and some tips too.

Can Lanoguard Be Used on a Galvanised Chassis?

Yes – but with care. New galvanised metal must weather for 2 years before applying Lanoguard. Applying too early can interfere with the natural protective oxidisation process. For smaller galvanised parts like brackets or fittings, test first to ensure proper curing.

Chassis Rust Protection FAQs

No. Lanoguard is a rust arrestor and preventer. It halts rust in its tracks by sealing it off from air and moisture.

One annual application is typically all that’s needed. You can reapply more often if desired – it builds deeper protection with each application.

Absolutely. In fact, it’s ideal for protecting welded areas before they start rusting again.

Drips should be minimal if applied correctly - only a thin layer is needed. We do offer a Driveway Protection Sheet to help protect your driveway from any drips and overspray.

Yes – without 360 Injector Wand designed to apply internally, into box sections, sills and those hard to reach areas.

Ready to Protect Your Chassis?

Don’t wait until the MOT fail — stop rust before it starts. Whether you're dealing with surface rust or wanting to maintain your vehicle, Lanoguard offers the smart, modern solution.

General Frequently Asked Questions

Find answers to common questions and learn more about Lanoguard's products, applications, and benefits.

Moto Range is designed for all vehicles, bikes, trailers and machinery to name a few. It protects the whole vehicle underbody and chassis from rust, corrosion and electrolysis with a strong barrier coat. Find out more and see our Moto Range.

Marine Range is designed for boats and any machinery submerged in sea water. It protects from rust, corrosion and electrolysis the same as our Moto Range, but also contains marine growth inhibitors to stop barnacle build up on any equipment submerged in seawater. It is safe, non-toxic and marine ecology friendly. Some of its uses include on outboard and inboard motors including electrics, propellers and prop shafts and boat trailers. Find out more

Outdoor Range is a thinner formula, designed for metal, rubber, vinyl, wood, and almost all materials. It can be used on BBQs, sheds, fences and decking to name a few. It provides protection from corrosion, rust and waterproofs as wells preventing mould build-up in woods and vinyls due to it containing anti-fungal. Find out more

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.
