Infiniti Medium Blue Metallic (B21) Touch Up Paint

The Look

This shade defined a specific era for the G35 and G37, offering a sophisticated alternative to the more common greys and blacks. It carries a depth that feels upscale rather than flashy, giving your car a presence that still holds up on the road today. Since your Infiniti has likely spent over a decade facing the elements, the original finish might have lost some of its vibrance. A fresh application helps restore that factory crispness, but remember that older paint can darken or fade slightly, so your goal is to blend the new color into the existing character of the panels.

Technical Details

This is a true metallic finish, which means it relies on tiny flakes to catch the light and create that signature shimmer. The challenge with any metallic is preventing the flakes from bunching up or settling unevenly. If the flakes are not distributed correctly, you will see dark patches or light streaks that make the repair stand out for the wrong reasons. Because the metal particles are heavier than the pigment, they want to sink to the bottom of your container, so your success depends on keeping the mixture active while you work in your garage or the shade.

Best Practices

You can usually find your identification plate on the driver-side door jamb or located on the firewall inside the engine compartment. Before you spray or dab Infiniti Medium Blue Metallic (check for code B21), you need to shake the container for at least two full minutes. This ensures the metallic flakes are suspended evenly in the paint. Test the color on the included card to verify the match before touching the car. When you apply the paint, keep the container moving and use light, overlapping layers. Avoid the temptation to cover the spot in one go; thin coats allow the flakes to lay flat and prevent the finish from looking muddy. Give the paint plenty of drying time between layers to ensure a durable bond.
