GMC Catalina Blue Metallic (25 (1976)) Touch Up Paint

The Look

This shade is a hallmark of the mid-to-late seventies GMC lineup, particularly the Sierra and Suburban models that defined the Square Body generation. Since your truck has likely been on the road for several decades, the original finish has probably mellowed into a softer, more dignified blue. It is a working man's color with enough metallic depth to look sharp after a wash. It strikes a balance between a utility vehicle and a weekend cruiser, offering a dark enough tone to hold its ground without the aggression of a modern navy.

Technical Details

This is a true metallic finish, which means your repair success depends entirely on how those tiny flakes lay down. If you apply the paint too heavily in one spot, the metallic particles will sink and create dark, muddy patches. If you apply it too lightly, the repair might look thin or silvered. Metals also tend to settle at the bottom of the container quickly. If you do not keep the container moving while you work, the color will shift from the first stroke to the last. This mismatch happens because the flake density changes as you use the product.

Best Practices

Before you spray or dab GMC Catalina Blue Metallic (check for code 25 (1976)), you need to shake it for 60 seconds. You will find your paint code on the silver Service Parts Identification sticker, which is almost always located inside the glove box door on these trucks. Test the color on the included card to see how it reacts to your specific lighting in the garage or shade. When you are ready to begin, apply thin layers and allow ample drying time between each one. If you are using a pen or brush, avoid the temptation to "paint" back and forth; instead, dab the color into the center of the chip and let it flow to the edges.
