GMC International Blue Pri Metallic (30/377E) Touch Up Paint

The Look

This color is a rare find from the 2001 model year. It was part of the GMC Special Colors collection, meaning your vehicle likely served a specific fleet purpose or was part of a limited promotional run. It is a deep, professional blue that carries a lot of visual weight. Since your Sierra or Yukon has been on the road for over two decades, the original finish has seen plenty of sun and weather. Restoring it requires a color that matches that specific gravity and depth to make the repair disappear into the surrounding panels.

Technical Details

This is a metallic finish, which means the paint is filled with tiny flakes that catch the light to create a three-dimensional effect. The benefit of this metallic structure is that it hides small surface dust and minor imperfections better than a solid color. However, these flakes are heavy and tend to settle at the bottom of the container. If they are not distributed into the liquid, the repair will look too dark or blotchy. You want the flakes to lay flat and even so the light reflects off the surface just like it did when the truck left the factory.

Best Practices

Before you spray or dab GMC International Blue Pri Metallic (check for code 30/377E), you need to shake it for at least 60 seconds. You can verify your color match by looking at the Service Parts Identification sticker, which is almost always located inside your glove box. When you start the repair, work in a cool garage or the shade to prevent the paint from drying too fast. Apply several thin layers rather than one heavy coat, and give the paint enough drying time between each pass. Test the color on the included card first to ensure the flake density is correct. To get a uniform look, keep the container moving across the surface at all times.
