Kia Mercury Blue Pearl (BU2) Touch Up Paint

The Look

Your Sportage carries a sense of maturity with this specific shade of navy. It is a deep, moody blue that often mimics black under a cloudy sky but wakes up with a vibrant glow the moment the sun hits it. This color was a defining choice for the 2017-2022 Sportage era, offering a premium alternative to the standard grayscale options. Since your vehicle has spent several years facing the elements, the original finish might have darkened or lightened slightly compared to a fresh batch, so you should approach your repair with a focus on blending rather than a single heavy application.

Technical Details

This is a true pearl finish, which is fundamentally different from a standard solid or metallic paint. It relies on tiny mica particles to catch and refract light at different angles. The challenge with a pearl like this is that the mica settles very quickly. If you do not mix it thoroughly, you will find the color looks flat or dull once it dries. Additionally, applying the paint too thick in one pass will cause those mica particles to bunch up, creating a dark spot that ruins the depth of the repair. You want to aim for thin, consistent layers that allow the pearl effect to sit evenly across the surface.

Best Practices

You will find your paint code on a black sticker located inside the driver's side door jamb. Before you spray or dab Kia Mercury Blue Pearl (check for code BU2), you need to shake it for at least sixty seconds to ensure the mica is fully suspended. Test the color on the included card to get a feel for the flow and how the shade builds with each layer. Whether you are using a pen or a can, keep the container moving to prevent the paint from pooling. Give each layer enough drying time so the surface isn't tacky before you move on to the next. Finishing with a clear coat is vital here, as the pearl particles need that extra layer of transparency to truly pop.
