Buick Rainier Touch Up Paint (41 OEM Colors)

The Color Breakdown

Buick clearly wanted the Rainier to look as premium as it felt, because they loaded the catalog with a staggering 41 colors. We aren't just talking about your standard "Rental Car Silver" here; they went for high-drama tones like Emerald Jewel Metallic, Dark Cherry Metallic, and Bordeaux Red. It's a sophisticated palette that says, "I'm here for the suburban commute, but I'd look great parked at a vineyard." Even the greys have personality, with names like Stealth Grey and Spiral Gray making the monochrome life feel a bit more like a secret agent's garage.

What to Watch For

Before you start dabbing, you need to find your "Service Parts Identification" sticker. Don't go hunting around the door frame like most cars; Buick tucked the Rainier's paint code safely inside the glovebox. Look for a code starting with "WA" or "U" (for Upper).

As for the paint itself, these SUVs are known for "sun-seeking" clear coat issues. If you notice a cloudy or flaky look on the hood or the roof, that's just the clear coat getting tired of the UV rays. You might also see little bubbles starting around the liftgate handle-that's a classic GMT360 platform quirk. The good news? Catching those chips early with a touch-up pen is exactly how you stop a small flake from becoming a hood-sized headache.

Driveway Repair Tip

Since so many of these colors are "Metallics" or "Effects," they are packed with tiny flakes that provide that signature Buick shimmer. If you just open the bottle and start painting, all that glitter stays at the bottom, and your repair will look flat. Shake your touch-up bottle for a full two minutes-long after you think you're done-to get those metallic flakes dancing again. When applying, think "thin and patient." It is much better to apply three whisper-thin layers than one big, gloopy teardrop that takes three days to dry.
