Corrosion is one of the most persistent and costly challenges in the automotive industry. Whether you’re manufacturing new vehicles, restoring classics, or operating a commercial fleet, protecting metal components from rust and degradation is vital for safety, longevity, and performance.

In the UK—where rain, road salt, and high humidity are constant threats—effective corrosion protection isn’t optional. It’s essential. That’s why more automotive businesses are turning to advanced coatings like powder coating and Cerakote ceramic coatings to combat corrosion and extend the life of their vehicles and components.

Why Corrosion is a Serious Problem in the Automotive Sector

Corrosion doesn’t just make vehicles look unsightly—it can cause structural failure, increased maintenance costs, and safety hazards. Once rust sets in, it spreads rapidly, especially in the UK’s wet climate and gritted winter roads.

Common issues caused by corrosion include:

Chassis and suspension component failure
Brake line and fuel system degradation
Exhaust system rust-through
Cosmetic damage to body panels and wheels

Whether you’re in automotive manufacturing, performance tuning, or fleet maintenance, corrosion protection should be a key part of your process.

How Coatings Prevent Automotive Corrosion

To stop rust before it starts, you need to shield the metal from moisture, oxygen, and road chemicals. That’s where protective coatings come in. By forming a durable, impermeable barrier, they prevent the conditions needed for corrosion to take hold.

🔩 Powder Coating for Corrosion Protection

Powder coating is one of the most effective and widely used methods in the automotive industry for corrosion prevention.

Key Benefits:

Tough, chip-resistant finish
Resists road salt, moisture, and debris
Ideal for wheels, chassis components, brackets, and suspension arms
Eco-friendly—no VOCs or solvents

When paired with proper surface preparation (like vapour blasting), powder coating provides a long-lasting, rust-resistant finish for automotive parts exposed to the elements.

🛡 Cerakote Ceramic Coatings: Advanced Corrosion Defence

For high-performance or high-risk applications, Cerakote ceramic coatings offer even more protection. Originally developed for aerospace and military use, Cerakote is now a top choice for automotive parts requiring extreme durability and precision.

Why Cerakote Stands Out:

Superior corrosion resistance even in salt-spray conditions
Ultra-thin application (ideal for close-tolerance parts)
Withstands chemicals, oils, and fuels
High heat resistance for use on exhausts, turbo housings, and brake components
Available in a wide range of colours and finishes

It’s perfect for parts that face high heat, road grime, and chemical exposure—such as exhaust manifolds, engine parts, underbody brackets, and brake calipers.

Protective Coating Use Cases in the Automotive Industry

At Supreme Coatings LTD, we work with garages, restorers, and manufacturers across the UK to provide rust protection solutions that last. Common applications include:

Powder coating for wheels, wishbones, subframes, and roll cages
Cerakote for turbochargers, headers, brake calipers, and engine components
Vapour blasting to prep surfaces and remove corrosion before coating

The Long-Term Value of Corrosion Protection

Investing in professional coatings may seem like a small detail, but the benefits are big:

✅ Increased component lifespan
✅ Lower maintenance costs
✅ Improved resale value
✅ Enhanced safety and performance
✅ Stronger customer confidence in your builds or products

For fleet operators, it means fewer breakdowns and repairs. For enthusiasts and builders, it means longer-lasting restorations. For manufacturers, it means more durable, high-quality parts off the production line.

Corrosion Resistance in Aerospace: The Role of High-Performance Coatings

In the aerospace industry, corrosion is more than just a maintenance issue—it’s a serious safety concern. Whether you’re building commercial aircraft, military systems, or unmanned drones, protecting components from corrosion is critical to ensuring airworthiness, structural integrity, and long-term performance.

With exposure to extreme weather conditions, fluctuating altitudes, UV radiation, salt-laden environments, and aggressive cleaning chemicals, aerospace components need coatings that perform well beyond conventional standards. This is where high-performance coatings like Cerakote ceramic coatings and advanced powder coatings come into play.

Why Corrosion is a Major Risk in Aerospace Engineering

Aircraft operate in some of the harshest environments on earth—and above it. Components are regularly exposed to:

Moisture from rain, humidity, and condensation cycles
Salt air and de-icing chemicals at airports
Fuel, oil, and hydraulic fluid exposure
UV degradation from high-altitude sunlight
Rapid pressure and temperature fluctuations

These conditions can accelerate oxidation, pitting, galvanic corrosion, and material fatigue, especially in aluminium, magnesium, and steel alloys. If left unchecked, corrosion can:

Compromise structural strength
Affect aerodynamic performance
Increase maintenance costs and downtime
Lead to costly repairs or even in-flight failure

The Solution: High-Performance Coatings for Aerospace Corrosion Protection

To counteract corrosion, aerospace manufacturers and MRO (maintenance, repair, overhaul) teams rely on advanced coating systems that seal surfaces, block moisture, and resist chemical attack.

🛡 Cerakote Ceramic Coatings

Cerakote is an ultra-durable, thin-film ceramic coating originally designed for defence and aerospace applications. It offers superior corrosion protection while being incredibly lightweight and heat-resistant—a perfect match for aerospace use cases.

Key Benefits:

Corrosion tested to over 3,000+ hours in salt spray environments
Ultra-thin application (0.5–1 mil) – ideal for weight-sensitive aerospace components
Resistant to hydraulic fluids, de-icing chemicals, jet fuel, and solvents
Protects aluminium, titanium, steel, magnesium, and composites
Extremely hard and abrasion-resistant – prevents mechanical damage that can lead to corrosion points

Common aerospace uses for Cerakote include:
✈️ Exhaust shields, engine parts, brackets, control surfaces, landing gear, and drone chassis.

⚙️ Powder Coating for Aerospace Hardware

Powder coating is another high-performance solution, particularly for non-flight critical parts or ground support equipment.

Advantages in aerospace include:

Tough, chip-resistant barrier against environmental and chemical exposure
Excellent corrosion resistance for structural steel and aluminium alloys
No solvents or VOCs – suitable for environmentally conscious aerospace supply chains
Durable finish for control panels, housings, frames, and aircraft interiors

When applied over properly prepared substrates—often cleaned and profiled by vapour blasting—powder coating can significantly increase the service life of aerospace hardware.

Meeting UK Aerospace Standards

In the UK, aerospace coatings must meet rigorous requirements set by industry bodies such as BSI, EASA, and MOD specifications. Coating systems like Cerakote not only meet but often exceed military-grade and aviation standards for corrosion and environmental resistance.

✅ Compliant with REACH and RoHS regulations
✅ Meets or exceeds MIL-SPEC standards for corrosion, wear, and chemical resistance
✅ Suitable for use on components under strict weight and thickness tolerances

Reducing Costs, Increasing Safety

Using high-performance coatings isn’t just about preventing rust—it’s a cost-effective strategy that:

Reduces inspection frequency and maintenance labour
Prevents component failure and unplanned downtime
Improves safety and reliability over the aircraft’s lifetime
Increases the lifespan of both critical and auxiliary parts

Conclusion: Coatings are a Critical Line of Defence

In aerospace, corrosion is inevitable—but preventable. With the right protective coatings, manufacturers and engineers can drastically reduce the impact of corrosion, boost operational efficiency, and protect high-value components in some of the most demanding conditions known to man.
