Your Paint Color Profile

503 (1973) - Light Blue

The Look

This color is the definitive "welcome home" for the first year of the Square Body generation. If you own a 1973 GMC, this shade represents the shift toward the modern truck era, moving away from the rounded lines of the sixties into a more rugged, utilitarian aesthetic. It is a humble, nostalgic blue that feels at home on a farm or a job site. Because your truck has been on the road for over half a century, the original finish has likely taken on a matte, chalky character from years of sun exposure. This means any fresh paint will naturally look more vibrant and deep than the aged panels around it, so focusing on blending is your primary goal.

Technical Details

This is a solid finish, meaning there are no metallic flakes or pearls hidden in the mix. The absence of metal particles is a massive advantage for a garage repair because you do not have to worry about mottling or the "tiger stripes" that occur when flakes settle unevenly. You get a consistent, flat blue tone every time. However, solid colors like this are honest-they show every bit of texture and surface prep. If the area you are fixing is not perfectly smooth, the solid blue pigment will highlight the edges of the scratch. Since this is a lighter value, it hides dust well, but it requires a clean, grease-free surface to ensure the new pigment bites into the old finish.

Best Practices

You will usually find your identity sticker on the inside of the glove box door; look for the Service Parts Identification label to confirm your match. Before you spray or dab GMC Light Blue (check for code 503 (1973)), you need to shake the container for at least sixty seconds to ensure the heavy solid pigments are fully suspended. Always test the color on the included card to see how the new paint looks next to your specific level of vintage patina. When applying, keep the container moving and focus on several thin layers rather than one heavy coat. Thin layers prevent runs and allow you to control the drying time, which is much safer in a standard garage or shade than trying to rush a thick application.

ensuring the right match

How to Find Your GMC's Color Code

GMC placed paint codes in many different locations, making them difficult to find, and GM did not standardize the color plate location across makes and models. Codes are often found in the glove box or the spare tire well; otherwise they could be elsewhere. Typical format: 51/WA316N, usually preceded by BC/CC (e.g., BC/CC 51 or BC/CC 316N). Two-tone entries may use U or L for Upper or Lower (e.g., BC/CC U316N or BC/CC L316N).

Will absolutely order from this company again.

After ordering touch-up paint from Lexus I was still waiting for it a month later. If they'd told me upfront it would take that long I wouldn't have ordered in the first place. Paint Scratch was recommended by a friend who restores cars. Easy ordering, fair price and fast shipping. The color match is great especially considering my car is a 2012. Will absolutely order from this company again. Reason I chose this business: Lexus collision repair and a local collision repair. Will use paint less dent removal and touch up chipped paint myself. Reason I chose this product: Spouse sideswiped passenger side of car while backing out of garage. Mostly plastic transfer from his wheel well trim but pressure creased and cracked the paint causing a bare strip 1/8 wide x 4" long below door handle. Scratches on door handle and a few small chips on both doors.

Simply the best custom mixed paint in spray cans

Used Paint Scratch metallic custom mixed spray cans paint on a hood panel with excellent coverage and texture over the surface. Metallic paint can be very unforgiving out of a spray can, sputtering pigmentation dots on the panel being sprayed and thus ruining the paint job. No such issues with Paint Scratch custom mixed metallic paint spray cans. Paint sprayed strong and evenly till the last drop of paint in the can. Shipping time was faster than expected. Reason I chose this business: Having tried other brands of custom mixed metallic paint with terrible results, sputtering pigmentation tint dots from the spray nozzle in spite of vigorously shaking of can prior to application and loss of propellant rendering the lower fifth of the can's paint useless, Paint Scratch custom mixed metallic paint sprays out beautifully and strong all the way to the last gram of paint in the can. Simply the best custom mixed paint in spray cans for automotive restoration. Thank you Paint Scratch.
