Your Paint Color Profile

WA803T - Light Platinum (Interior)

The Look

You likely see this refined silver-grey trim every time you reach for the door handle or adjust the vents in your Terrain. This color was a centerpiece for the 2018 cabin redesign, meant to provide a cool, technical contrast to the darker upholstery. Because it sits on high-traffic areas like the center console and door bezels, it takes a beating from rings, keys, and coffee cups. Since your GMC has been on the road for several years now, these silver accents often show the first signs of cabin wear, but the neutral tone makes it a forgiving color to restore if you match the factory sheen.

Technical Details

This is a fine-grain metallic finish designed for interior plastics. Interior metallics are different from exterior paints because they use much smaller flakes to avoid looking glittery under cabin lights. The challenge here is pigment settling. The heavy metallic particles sink to the bottom of the container quickly. If you do not mix it thoroughly, the paint will come out looking like a flat grey rather than a crisp platinum. This can lead to a patchy appearance where the repaired spot looks darker than the surrounding trim. You need to keep the metallic flakes suspended to get that factory-correct glow.

Best Practices

You can find your paint information on the silver Service Parts Identification sticker, usually located on the driver side door pillar or inside the glove box. Before you spray or dab GMC Light Platinum (Interior) (check for code WA803T), you must shake the container for two full minutes. This isn't just a suggestion; it is the only way to ensure the silver flakes blend with the pigment. Test the color on the included card first to verify the metallic density. When you begin, keep the container moving across the surface to prevent the paint from pooling. Applying three thin layers is always better than one thick one, so give the trim plenty of drying time in the shade before you touch the surface.

ensuring the right match

Find your GMC paint 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.
