GMC Rowan Tricoat (WA326E/WA429E/GLR/GNL) Touch Up Paint

The Look

This color is one of the more sophisticated finishes GMC has put on the road recently. Whether it is on a Sierra or an Acadia, this deep, rich red carries a level of depth that you just do not get with standard metallic paints. It was a short-lived option for the 2020 and 2021 model years, often appearing under different marketing names like Black Cherry or Cayenne Red. Because your vehicle has likely been through a few seasons of sun and road debris, you will notice that this color has a heavy pearl effect that changes depending on the light hitting the panels. It is a high-end look, but that complexity means it requires a bit more focus during the repair than a flat white or silver.

Technical Details

This is a pearl metallic tricoat, which is the most challenging finish to mimic perfectly. Unlike a standard paint that uses a single color layer, this system relies on a base coat followed by a translucent mid-coat that contains the pearl. This mid-coat is where the magic happens, but it is also where things can go wrong. If you apply too many layers of the mid-coat, the color will become too dark and muddy; if you apply too little, the repair will look flat and won't catch the light. Before you spray or dab GMC Rowan Tricoat (check for code WA326E/WA429E/GLR/GNL), you need to shake it for 60 seconds to ensure the metallic flakes and pearl pigments are evenly distributed.

Best Practices

To find your confirmation sticker, check the glove box first. For most GMC models like the Canyon or Sierra, the silver service label is located right inside that compartment. If you are driving a Savana van, you might need to look under the driver's seat or on the rear face of the door pillar. When you are ready to work, move your vehicle into a garage or a patch of shade. Test the color on the included card first to see how many layers of the mid-coat you need to reach the right depth. When applying the paint, keep the container moving at a steady pace to avoid heavy spots. Give each layer plenty of drying time before moving to the next. If you are using a pen, use light dabs rather than long strokes to keep the pearl from clumping.
