Mercedes-Benz Onyx Black Metallic (346/9346) Touch Up Paint

The Look

Mercedes-Benz didn't just pick another black when they designed this for the S-Class and the EQS. This is a flagship finish. It carries the weight and authority of a Maybach gliding through the city at night. Unlike a standard flat black, it has a depth that feels like looking into a deep pool of water. It is intense and dramatic, specifically designed to accentuate the long, flowing lines of a high-end luxury cruiser. Since your vehicle was built to represent the pinnacle of the brand, this color demands a repair that respects its heavy presence.

Technical Details

This is a true metallic finish. It relies on a suspension of fine flakes to create that signature luster. The challenge with such a dark metallic is that those flakes love to settle at the bottom of the container. If you don't mix them well, the color will look dull or patchy once it dries. Because the base is so dark, any heavy spots will cause the metallic particles to cluster and sink, which creates a mottled, bruised look on your repair. You need thin, even layers to keep the sparkle uniform and consistent with the factory finish.

Best Practices

Before you spray or dab Mercedes-Benz Onyx Black Metallic (check for code 346/9346), you need to shake the container for at least 60 seconds. You can find your specific paint code on a sticker located inside the driver-side door jamb. Test the color on the included card before you touch the car to ensure the flake density is right. Keep the container moving while you apply the paint to prevent it from pooling in one spot. If you are using a pen or brush, avoid overloading the tip. Give each layer enough drying time so the metallic particles set correctly before you apply the next coat.
