COLOR CODE703A/731 (1960) - Neptune GreenGMC Touch-Up Paint

The Look

This color is the definitive personality of the 1960 GMC truck line. It sits right in that sweet spot between a seafoam teal and a deep forest green, capturing the utilitarian optimism of the early sixties. Since your truck has been on the road for over six decades, this shade has likely become part of its character, whether it has stayed deep and rich or mellowed into a chalky vintage patina. It is a hardworking color that was designed to look just as good covered in dust at a job site as it did sitting on a showroom floor.

Technical Details

This is a classic solid finish, which means you do not have to worry about metallic flakes settling unevenly or creating stripes. The challenge with a solid green like this is that it can be very honest about the surface underneath. If your prep work isn't smooth, the finish will show it. Because this color has likely been exposed to the sun since the Eisenhower administration, the original paint on your panels may have shifted in tone. A solid color is easier to blend than a pearl, but you still need to be mindful of the depth to ensure your repair does not look like a dark patch on a lightened fender.

Best Practices

You can usually find your paint information on the Service Parts Identification plate located inside the glove box or on the driver's side door pillar down by the floor. Before you spray or dab GMC Neptune Green (check for code 703A/731 (1960)), you need to shake it for 60 seconds to ensure the pigments are fully integrated. Test the color on the included card to verify the match against your specific truck's current condition. When applying, keep the container moving to avoid heavy buildup in one spot. If you are using a pen or brush for chips, build the color in thin layers and allow plenty of drying time between each pass to prevent the paint from sagging.
