Underbody Rustproofing

Protect your vehicle from rust, corrosion and long term structural damage with professional underbody rustproofing carried out by experienced specialists.

At Trickett Welding, we use professional grade Wurth rust converter and underbody wax to deliver durable protection that lasts far longer than standard underseal treatments.

Rustproofing is one of the most effective ways to preserve your vehicle’s structure, safety and value — particularly in the UK’s damp climate.

What Is Underbody Rustproofing?

Underbody rustproofing is a specialist process that protects the structural components of your vehicle from corrosion.

In the UK, vehicles are constantly exposed to moisture, road salt and debris which can lead to rust developing underneath the vehicle. Over time, corrosion can weaken structural components, reduce safety and lead to MOT failures if left untreated.

While most vehicles leave the factory with some protection, this coating rarely provides long term defence against corrosion. Professional rustproofing adds a durable barrier that protects vulnerable areas where moisture and road grime collect.

What products Are used?

Many people refer to rustproofing as “Waxoyling”. However, Waxoyl is actually a brand name that has become widely used to describe the job itself.

At Trickett Welding we do not use Waxoyl products. Instead, we use professional grade Wurth rust converter and underbody wax which offers superior adhesion, durability and long term corrosion protection.

Vehicles are carefully covered with protective polythene masking film before any grinding or product application, safeguarding exhausts, brakes, and surrounding components.

Benefits of Professional Rustproofing

Proper rustproofing provides several long term benefits for your vehicle:

Prevents Corrosion In Key Structural Areas
Protects Hidden Cavities Such As Sills And Inner Arches
Improves Vehicle Safety By Preventing Rust Related Weakening
Stops Rust Spreading Further Across The Vehicle
Maintains The Vehicle’s Resale Value
Provides Long Term Protection Against The Uk Climate And Road Salt

A Fully Equipped Vehicle Workshop

Unlike quick spray treatments offered elsewhere, our rustproofing service involves thorough preparation and a multi stage application process.

Full Underside Preparation

We begin by removing underbody trims and wheel arch liners. The entire underside of the vehicle, including inner arches, is prepared so that all metal surfaces can be treated effectively.

Proper preparation ensures the protective coatings adhere correctly and reach every vulnerable area.

Rust Inhibitor Treatment

All exposed metal surfaces are treated using Wurth chemical rust converter. This neutralises existing rust and prevents further corrosion developing.

The treatment is applied thoroughly to ensure it reaches seams, joints and hidden cavities.

Protective Underbody Wax

Once the rust converter has fully cured, we apply Wurth underbody wax.

This coating creates a flexible, waterproof barrier that protects against moisture, salt and road debris while resisting cracking or flaking over time.

Final Reassembly & Inspection

After treatment, all trims and components are refitted and the vehicle is checked to ensure everything is correctly installed and ready for collection.

Full Photographic Documentation

Our rustproofing service typically takes 4–5 days to complete and includes photographic documentation so you can see exactly what work has been carried out.

Why Choose Trickett Welding?

Many companies offer quick underseal treatments that simply spray over existing surfaces. Our approach focuses on long term protection and proper preparation. Reasons customers choose Trickett Welding include:

Thorough Preparation And Application Process
Premium Wurth Rust Protection Products

The workshop has a 5-tonne ramp and sufficient height clearance to work on larger vehicles.

Vehicles Suitable for Rustproofing

Rustproofing can benefit a wide range of vehicles including:

Motorhome Rust Protection Work

Motorhomes need proper rust protection to prevent long-term damage from moisture, road salt, and changing weather. Motorhomes are often left unused or stored in damp conditions and benefit from corrosion. Regular inspections and protective treatments help preserve the chassis, reduce repair costs, and extend the vehicle’s lifespan.

Frequently Asked Questions

How long does rustproofing take?

The duration of the rustproofing process varies depending on the size, age and overall condition of your vehicle. Following a detailed inspection, our specialists will assess your vehicle’s specific requirements and provide a precise timeframe based on the work required.

To ensure a seamless experience, we offer complimentary courtesy cars, allowing you to continue your day uninterrupted while your vehicle is in our care.

Will rustproofing stop existing rust?

This depends on the extent of the corrosion present. Our advanced treatment process uses Würth rust converter, which penetrates deep into affected areas and chemically reacts with the corrosion, transforming iron oxide into a stable, insoluble metal-organic compound. This creates a solid foundation that can then be sealed and protected with a high-quality underbody wax coating.

In cases of more advanced corrosion, where the structural integrity of the metal may be compromised, we may recommend a welding repair to restore strength and safety. This service can be carried out seamlessly in-house by our experienced technicians, ensuring your vehicle receives the highest standard of care from start to finish.

Is rustproofing worth doing on newer cars?

Absolutely. Prevention is always more cost-effective than cure. By protecting your vehicle before corrosion has the chance to develop, you are safeguarding its condition, longevity and value for years to come.

It is also important to consider that many vehicles imported from warmer climates often leave the factory with minimal or no anti-corrosion protection. When exposed to the harsher UK climate, these vehicles can deteriorate far more rapidly than expected.

At Trickett Welding, we ensure that modern vehicles receive the same meticulous level of care and protection as classic models, delivering long-term peace of mind through expert workmanship and premium materials.

How long does rustproofing last?

Our processes are designed to deliver the highest standard of long-term protection. The longevity of rustproofing will naturally depend on factors such as vehicle usage, mileage and the conditions it is exposed to.

With many years of experience, we have seen vehicles treated with our system remain in excellent condition for 10 years or more. To maintain optimal protection, we recommend periodic inspections, allowing us to assess the coating and reapply protection to high-wear areas where road wash may occur.

It is also worth noting that some popular DIY products, such as Lanoguard, are not engineered to provide true long-term protection. These treatments can mask underlying issues rather than properly addressing and resolving corrosion at its source.

At Trickett Welding, we focus on delivering durable, professional-grade solutions that protect your vehicle properly, both now and in the years ahead.
