COLOR CODE503 (1965) - Light GreenGMC Touch-Up Paint

The Look

This color is the quintessential mid-century utility shade. It carries a soft, minty character that defined the working class GMC trucks of the mid-sixties. Because your truck has been facing the elements since 1965, the original finish has likely shifted toward a flatter, chalkier tone. This light pastel green is famous for its clean, industrial aesthetic, looking just as right on a restored show pony as it does on a weathered farm hand. It is a humble color that highlights the heavy steel lines of your truck without demanding too much attention.

Technical Details

This is a solid finish, which is excellent news for your repair project. Unlike metallic paints that require perfect orientation of tiny flakes, this solid pigment is much more forgiving. You do not have to worry about mottling or dark stripes appearing in the finish. The main challenge you will face is the "newness" of the fresh paint compared to the aged sections of the vehicle. Since there is no metallic sparkle to hide behind, any difference in shade caused by decades of sun exposure will be visible, so focus on blending your edges into the surrounding panels.

Best Practices

You can typically find your identification plate inside the glove box door or occasionally on the firewall. Before you spray or dab GMC Light Green (check for code 503 (1965)), you need to shake it for 60 seconds. This ensures the heavy green and white pigments are fully integrated. Test the color on the included card to see how it sits next to your existing finish. When applying, keep the container moving to ensure an even layer and avoid heavy buildup. If you are working in your garage or a patch of shade, give the paint plenty of drying time between coats to prevent sagging.
