Paint defects explained

Common Paint Defects and What Causes Them - By The Coating Lab – Paint Correction Auckland Experts

When it comes to maintaining your vehicle’s appearance, nothing is more frustrating than noticing swirl marks, scratches, or dull patches in your paintwork. These paint defects not only ruin your car’s finish but can also lower its resale value if left untreated.

At The Coating Lab, we specialise in paint correction in Auckland, restoring your vehicle’s paint to a flawless, showroom-quality finish. Whether you're dealing with minor imperfections or deep scratches, understanding what causes paint defects is the first step in preventing them.

In this blog post, we break down the most common paint defects we see in our workshop—and what you can do to avoid them.

🎯 1. Swirl Marks: The Most Common Culprit

What they look like: Fine, circular scratches visible under sunlight or showroom lighting.

What causes them:

• Improper washing or drying techniques

• Using dirty or low-quality microfiber cloths

• Automatic car washes with abrasive brushes

How to fix it:
Swirl marks can be professionally removed with a multi-stage cut and polish treatment. At The Coating Lab, we use advanced polishing systems to safely eliminate swirl marks without thinning your clear coat.

🔧 2. Oxidation: When Paint Loses Its Shine

What it looks like: Faded, chalky or dull paint—often on the roof, bonnet, or boot.

What causes it:

• Prolonged UV exposure

• Lack of protective coatings (wax, sealant, or ceramic)

• Neglect over time

How to fix it:
Paint oxidation can be reversible with professional paint correction. A proper cut and polish will remove the oxidised layer and restore gloss, especially when followed by ceramic coating to prevent recurrence.

🚗 Auckland’s harsh UV levels make oxidation a major issue for unprotected cars—especially darker colours.

🕳 3. Deep Scratches and Scuffs

What they look like: Visible scratches that catch your fingernail.

What causes them:

• Accidental contact with shopping trolleys, bushes, or keys

• Improper washing tools

• Road debris and stone chips

How to fix it:
Deeper scratches often require paint correction using machine cutting and professional-grade compounds. In severe cases, paint touch-up may also be required.

💧 4. Water Spots & Mineral Staining

What they look like: Circular marks left behind after rain or water drying on the surface.

What causes them:

• Hard water with high mineral content

• Infrequent drying after washing or rain exposure

How to fix it:
Mild water spots can be removed with a clay bar and polish. Stubborn etching may need cut and polish services to level the surface and restore clarity.

🧼 5. Holograms & Buffer Trails

What they look like: Ghost-like patterns or arcs in the paint, visible under sunlight.

What causes them:

• Poor-quality machine polishing

• Incorrect use of rotary buffers or cutting pads

• Amateur detailing attempts

How to fix it:
These defects are best corrected by professionals. At The Coating Lab, our certified technicians use precision dual-action polishers and paint depth gauges to safely remove these marks—without risking over-polishing.
