GMC Dark Olive Poly (506 (1971)) Touch Up Paint

The Look

This deep, earthy green defines the rugged character of the 1971 GMC truck lineup. It is a color that feels right at home on a farm or a forest trail, capturing the transition from the utilitarian sixties into the more expressive seventies. Since your truck has likely spent over fifty years facing the elements, the original finish might have mellowed or darkened compared to a fresh batch. This shade is excellent at hiding light dust and road grime, but it really comes alive when you get it out of the garage and into the natural light where the depth of the green can show through.

Technical Details

This is a metallic finish, which in 1971 was often referred to by the "Poly" designation. The paint contains fine metallic flakes that give the color its dimension and character. These flakes are heavier than the pigment, meaning they want to sink to the bottom of the container the moment you stop moving. If you aren't careful, the metal can clump together and cause mottling, which creates dark patches or uneven stripes across the repair area. To get a uniform look, you need to ensure the flakes lay down flat and even across the surface.

Best Practices

You can usually find your paint information on the silver Service Parts Identification sticker located inside the glovebox door. Before you apply any GMC Dark Olive Poly (confirm you have code 506 (1971)), you must shake the container vigorously for at least sixty seconds to wake up those settled metallic flakes. Test the color on the included card to ensure the shade matches your current finish. When you begin the repair, keep the container moving at a steady pace to maintain a consistent flow. If you are using a brush or pen for a small chip, use light dabs rather than long strokes to keep the flakes from piling up. Work in a shaded area and allow plenty of drying time between thin layers to build the color properly.
