Mixing & Matching Car Paint Colours
Why Getting the Right Car Paint Colour Match Matters
Car paint colour matching is the process of identifying and recreating the exact paint colour on your vehicle. A precise match is crucial for maintaining your vehicle's appearance and resale value. When done correctly, the repair is invisible. When done poorly, it draws attention to damage and can reduce your car's value.
Getting a perfect match isn't as simple as buying paint with the same code. Sun exposure causes fading, factory batches vary, and metallic finishes change appearance at different angles. This is why professional help is essential.
Key Steps for Accurate Car Paint Colour Matching:
- Find Your Paint Code - Located on a sticker in your door jamb, under the bonnet, or in your owner's manual.
- Professional Colour Analysis - Specialists use spectrophotometers to account for fading and variations.
- Custom Mixing - Paint is precisely mixed to match your car's current colour, not just the original factory code.
- Surface Preparation - Proper cleaning, sanding, and priming ensure the new paint adheres and blends seamlessly.
- Expert Application - Multiple thin coats of basecoat followed by a 2K clear coat for durability.
Professional suppliers use advanced technology to create a custom formula that accounts for these factors. Without this equipment and expertise, DIY attempts often result in visible patches. Professional-grade products like Protec basecoat and 2K clear coat systems, combined with proper application, deliver results that last.
I'm James Maranis, and I've spent over 30 years working with automotive coatings. At Eastern Auto Paints, we've perfected the process of matching everything from standard factory colours to custom textured powdercoat finishes, and I'm here to show you why professional colour matching is the smarter choice for lasting results.
Why Finding Your Exact Car Paint Colour is Crucial
Getting the right paint colour for your car isn't just about aesthetics, it's about protecting your investment. A proper car paint colour matching job makes a repair invisible, preserving your vehicle's resale value. More importantly, correctly matched and applied paint seals exposed metal, preventing rust and corrosion.
Even a slight colour variation makes repairs stand out, drawing attention to damage that should be invisible. Think of it like wearing one black sock and one navy sock, up close, it's obvious something is off.
What is automotive paint colour matching and why is it important?
Car paint colour matching is the science of recreating your vehicle's exact paint shade. It's complex because your car's colour changes over time. Sun exposure causes fading, and factory batches can vary even for the same paint code. For metallic or pearlescent finishes, the colour shifts depending on the viewing angle, a phenomenon professionals call "flop and flip."
This is why buying paint based on the code alone is not enough. Professionals use tools like spectrophotometers to scan your car's current colour, creating a custom-mixed formula that matches what's on your car right now. This precision maintains your vehicle's market value and, when applied with the right primers and 2K clear coat, creates a protective barrier against the elements.
How can I find the paint code for my specific car?
Your car's paint code is a unique combination of letters and numbers identifying the factory colour. The location varies by manufacturer, but here are the most common places to look:
- Driver's side door jamb: Open the door and look along the frame for a sticker.
- Under the bonnet: Check the inner fender, radiator support, or firewall.
- In the boot: Look on the underside of the lid or near the spare tyre well.
- Glove box or owner's manual: Some manufacturers place it here.
Can’t find it? The team at Eastern Auto Paints can help. With 34 years of experience, we can track down your colour information. Just remember, the paint code is only the starting point, it does not account for sun fade or factory batch variations. This is where professional colour matching becomes essential. Using advanced spectrophotometers, we digitally analyse your car’s current colour and build a precise formula that blends seamlessly. And when technology is not enough, we have two full-time dedicated professionals who perform by-eye matching and fine tinting for a flawless result.

The Science Behind Professional Car Paint Colour Matching
Achieving a perfect car paint colour matching result is a fascinating blend of science, technology, and hands-on experience. It's far more complex than just looking up a paint code, which is why we've invested in sophisticated colour-matching technology at Eastern Auto Paints. Understanding the professional process helps you appreciate why it delivers superior results that can't be replicated at home.
What are the challenges in achieving a perfect car paint colour matching result?
Your car's paint code tells only part of the story. Several factors make matching your car's current colour tricky:
- Sun Fading: UV rays break down pigments, causing colours to fade and shift over time. A red car might develop an orange tint, while dark colours can become lighter.
- Factory Batch Variations: Slight differences can exist between paint batches, even for cars with the same code from the same production line.
- Metallic and Pearlescent Finishes: These paints contain particles that reflect light differently, causing the colour to change depending on the viewing angle (the "flop and flip effect"). Matching requires replicating the colour, size, and orientation of these particles.
- Environmental Factors: Road grime, pollution, and harsh cleaning chemicals can all alter the paint's appearance over the years.
How do professionals handle paint variations for the same code?
This is where professional car paint colour matching becomes truly scientific. We don't just rely on your paint code; we use advanced technology to analyse your vehicle's current paint condition.
Our spectrophotometer technology acts like a high-powered camera, digitally "reading" the colour by measuring the wavelengths of light reflected from the paint. This captures precise data on hue, saturation, and brightness, which our system uses to create a custom formula that accounts for fading and other variations.
We combine this digital precision with physical swatch card comparison. A trained expert eye is still invaluable, especially for complex finishes. Our technicians compare physical colour chips against your vehicle to confirm the reading and fine-tune the match. The final step is the tinting and blending process, where art meets science to create a flawless, invisible repair.

What is the difference between OEM and aftermarket paint codes?
OEM paint codes are the official codes from your vehicle's manufacturer, representing the formula used when the car was new. They tell you what the colour was, not what it is now.
Aftermarket paint codes are formulas developed by paint suppliers to match OEM colours. Quality varies, but premium suppliers use extensive analysis to account for real-world variations. At Eastern Auto Paints, we work with top brands like Protec Automotive Paint Systems and PPG Industrial Paints. Combined with our spectrophotometer technology, we create custom formulas that deliver results you can't achieve with a DIY approach. For a truly invisible repair, contact our team for a colour match that accounts for your vehicle's specific needs.
Choosing the Right Paint and Applicator for Your Repair
Getting the car paint colour matching right is only half the battle; choosing the correct paint and application method is the other. While we'll walk you through the options, achieving a professional finish requires experience, proper equipment, and a controlled environment that most home garages lack.
What are the different types of automotive paint available for touch-ups and repairs (e.g., aerosol cans, paint pens, bottles)?
We offer paint in several formats, each suited to different repair sizes:
- Paint pens are for the tiniest chips and fine scratches, allowing for precise application. However, achieving an invisible repair requires a steady hand and proper surface prep.
- Brush-in-bottles handle slightly larger scratches and chips. Like pens, the technique of feathering and building thin layers is crucial.
- Custom colour aerosol cans offer a professional-quality finish for larger repairs, but proper spray technique is essential. We can create custom aerosols for specific colours, including matches for the Dulux Elements, Textura, and Structura ranges, as well as Jotun powdercoat colours. These are available in our range of aerosol cans and custom aerosol cans.
- Paint in bottles and tins is used by professionals with spray guns for the most control and a factory-level finish. We supply acrylic mixed colours, basecoat mixed colours, and 2K mixed colours for these projects.
How do I choose the right paint type (e.g., lacquer, enamel) for my car's paint repair needs?
The type of paint system your vehicle uses determines the products you'll need, and professional expertise is invaluable here.
Modern vehicles use basecoat-clearcoat systems. The basecoat provides the colour, while a separate clear coat delivers gloss, UV protection, and durability. For these cars, you need a perfectly matched basecoat and a high-quality 2K clear for superior, lasting shine. However, 2K clear requires precise mixing and expert application to avoid imperfections.
Classic cars often have single-stage paints, where colour and gloss are combined. These require specific formulations and application knowledge to match correctly.
Beyond standard automotive jobs, we also supply specialised paints like vinyl paints and marine coatings. Epoxies for flooring, nitrocellulose for furniture, enamels, direct to metal topcoats.
the Full range from PPG and concept Paints, from radar cancelling topcoats to painting oil rigs to-spec out in the pacific, we can get it all.

A Pro's Guide to Surface Preparation and Application
The secret to an invisible paint repair lies in meticulous surface preparation and skilled application. As we often say, "We’ve found that most adhesion issues come down to poor surface prep." This is how professionals ensure a durable finish that lasts.
What preparation steps are necessary before applying touch-up paint to ensure a good result?
Proper preparation is non-negotiable for a professional result. Skipping these steps will compromise your repair.
- Clean the Area: Start by removing all dirt, wax, and grease with a dedicated wax and grease remover.
- Sand the Damage: For scratches or chips, use fine-grit sandpaper (e.g., 600-grit) to smooth the edges and create a surface for the new paint to adhere to. This "feathering" process ensures a smooth transition. You can find various sanding sheets and discs in our store.
- Apply Primer: If you've sanded to bare metal, a primer is essential for adhesion and corrosion protection. We recommend quality primers like EPO Epotec Primer Surfacer or Protec PPG Grey/Black Etch Primer. For deeper repairs, consider Protec Prime and Fill. Our full range of primers is also available.
What is the application process for different types of touch-up paint?
The process varies by product, but the core principles are thin coats, proper drying time, and a clear coat for protection.
- Paint Pens & Brush-in-Bottles: Apply very thin layers, allowing each to dry completely. Build up the colour gradually until it's level with the surrounding paint, then finish with a clear coat.
- Aerosol Spray Cans: Shake the can vigorously. Hold it 20-25 cm (8-10 inches) from the surface and apply in light, even sweeps. Apply 2-3 thin coats, allowing 5-10 minutes of drying time between each. some paints will need a topcoat clear others will not, once dry, apply 2-3 coats of 2K clear coat for durability.
- Spray Guns (Professional): Paint like Protec basecoat is mixed and applied with a professional spray gun, such as those from Anest Iwata, for even atomisation. After multiple thin coats, a 2K clear coat is applied for a hard, durable finish. We stock a range of Anest Iwata spray guns.
How can I ensure the longevity and durability of my paint repair?
- Proper Curing: Allow the paint to fully cure, which can take several days. Avoid washing the area during this time. Professionals may use heat lamps to speed up the process.
- High-Quality Clear Coat: A 2K clear coat is your best defence against UV rays and physical damage.
- Regular Maintenance: Once cured, regular washing and waxing will protect the paint and maintain its shine.
Special Cases and Environmental Regulations
Car paint colour matching extends beyond car bodies to specific parts and industrial applications, all while navigating important environmental regulations.
What are the considerations for painting specific car parts like wheels or engines?
Painting components like wheels and engines requires custom solutions for both appearance and durability.
- Wheels: Wheels need a durable finish to withstand road debris and brake dust. We offer specialized wheel paints and can create custom aerosols to match various powdercoat colours, including textured powdercoat colours.
- Engines: Engine paint must resist high temperatures, oil, and fuel. Standard automotive paint is unsuitable; a specific high-temperature formula is required.
- Industrial and Custom Projects: We can create custom aerosols for industrial colours, such as those from the Jotun or Dulux Elements (Textura, Structura) ranges. We also supply products like Galmet Rust Paint for rust prevention.
Are there any regional or state-specific regulations regarding automotive paint (e.g., VOC limits)?
Yes, environmental regulations concerning Volatile Organic Compound (VOC) limits are a key consideration. The Australian government provides guidance on VOC emissions, which affects the paints that can be sold and used.
We ensure our products are compliant and always advise customers on the best options for their projects. Safety is also paramount. Always use personal protective equipment (PPE), such as PPE masks or an Air Fed Mask, and ensure proper ventilation.
Where can I find reliable sources for OEM-matched automotive paint?
For a truly reliable match, it's best to work with a specialised automotive paint supplier. At Eastern Auto Paints, we combine over 34 years of experience with advanced spectrophotometer technology to create a custom paint formula that matches your vehicle's current colour, not just the original factory code. While online tools and manufacturer guides can help you find your code, they can't account for fading and other variations. For an accurate match and expert support, trust a professional supplier.
For any product, always refer to the manufacturer's Technical Data Sheet (TDS) and Safety Data Sheet (SDS) for detailed application and safety information. Our team can provide these for all products we supply.
What are the best practices for cleaning up and disposing of automotive paint products?
Proper cleanup and disposal are critical for safety and environmental protection.
- Cleanup: Clean tools immediately after use with the appropriate solvents. We offer a range of clean-up and recycling products.
- Disposal: Automotive paints and thinners are hazardous waste. Do not pour them down drains. Check with your local council in Victoria, Sydney, or Queensland for designated disposal points. For workshops, UNIC USD45XP-E Solvent Recycler or UNIC USD60XP-E Solvent Recycler machines can safely recover solvents, reducing waste and costs.
Frequently Asked Questions about Car Paint Matching
How do I choose the right paint for my car?
The best choice depends on your vehicle's paint system (modern basecoat-clearcoat or older single-stage), the size of the repair, and the desired finish. For an accurate match and professional advice on products like the Protec Automotive Paint Systems, it's best to consult with our expert team.
What is the difference between an OEM paint code and a professional match?
An OEM code represents the colour your car was when it left the factory. A professional match, created using a spectrophotometer, replicates the colour of your car today, accounting for years of sun exposure and environmental wear. This ensures the repair blends seamlessly with the surrounding aged paint.
What are the considerations for painting specific car parts like wheels or engines?
Specialty parts require specialty paints. Wheels need a durable, chip-resistant finish to handle road debris, and we can match powdercoat colours in custom aerosols. Engines require high-temperature paint that can withstand extreme heat and resist chemicals like oil and fuel.
