A-Pillar and B-Pillar Rust Protection — Arrest and Prevent Rust with Lanoguard

Stop A-Pillar and B-Pillar Rust in Its Tracks


If you’ve spotted rust creeping along your A-pillars or B-pillars — whether it's your MX5, Range Rover Classic, or VW T4 — you’re not alone. These structural pillars are notorious rust hotspots due to their exposure to moisture, road salt, and hidden cavities that trap water.

Common problem areas we help protect:

  • Range Rover Pillar Rusted: Especially around the A-pillar base and windscreen surround.
  • MX5 A-Pillar Rust: Often triggered by blocked drainage and moisture ingress.
  • VW T4 B-Pillar Nearside Rust: Vulnerable to seam corrosion and water traps.
  • General Pillar Rust: Corrosion often starts unseen, behind trim or weather seals, making early prevention essential.

Lanoguard offers a simple, effective way to stop pillar rust and prevent further damage without invasive repairs or complicated disassembly.

Why Do Pillars Rust So Easily?

Your vehicle’s pillars are exposed to:

  • Rainwater seeping behind seals
  • Salt spray during winter driving
  • Condensation build-up in hidden cavities
  • Paint cracks or stone chips allowing corrosion to take hold

Because these areas are hard to access, rust can spread quietly until major repairs are needed. That’s where Lanoguard makes a real difference.

How Lanoguard Protects Your A and B Pillars

Lanoguard is not a rust converter — it’s better. Our formulation arrests rust at source and blocks its development:

  • Creeps and seeps: Penetrates behind surface rust and forms a hermetic seal.
  • Moisture repellent: Keeps oxygen and water away, starving rust of what it needs.
  • Self-healing: Constantly active, it reseals tiny breaches automatically.
  • Long-lasting protection: Clear, soft, and non-cracking finish that stays active year-round.

Even if your pillars already show surface rust, Lanoguard can stop it progressing further, protecting both structural integrity and resale value.

How to Apply Lanoguard to Rusty Pillars

 Step-by-step application:

  1. Preparation: Clean the area and remove loose flaking rust (light brushing is fine; no need for full stripping).
  2. Dry: Ensure the surface i fully dry.
  3. Apply: Spray Lanoguard directly onto the A-pillar, B-pillar, and seams.
  4. Allow curing: Leave for 24 hours before driving. Full cure achieved in 7-10 days (Day 0 oily, Day 3 soft, Day 7 semi-satin candle-like finish).

A-Pillar & B-Pillar Rust Protection FAQs

Yes — while it won't convert rust, Lanoguard seeps under surface rust, seals it off from air and water, and prevents further spread.

No full stripping is required. Just remove loose flakes and ensure the surface is sound. Lanoguard is designed to bond directly to the surface and underneath remaining surface rust.

We recommend checking yearly and reapplying as needed. Many users find a single annual top-up keeps pillars fully protected.

Absolutely — Use Lanoguard's 360 Injector Wand, Its creeping nature allows it to reach hard-to-access internal seams and cavities.

Don’t let pillar rust silently weaken your vehicle’s structure or lead to costly repairs down the line. Lanoguard gives you peace of mind with simple, effective protection that keeps moisture out and rust at bay — year after year. Whether you're safeguarding a cherished MX5, a rugged Range Rover Classic, or a hardworking VW T4.

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.
