2018 GMC Background Info
The 2018 GMC Vibe
2018 was the year GMC decided to give their trucks and SUVs a sense of humor to match their chrome. If you were rolling a Sierra or a Yukon that year, you weren't just picking a color; you were picking a personality. With 60 colors in our database for this year alone, the factory was clearly keeping the mixing room busy. They moved away from the boring "Truck Gray" of yesteryear and leaned into punny, high-character shades like Black Meet Kettle Pearl, Blue Me Away Pearl, and the classic Old Blue Eyes Metallic. It was a sophisticated era where even the Acadia and Terrain were rocking complex finishes like Abalone White Tricoat-paints that looked like a million bucks under the dealership lights.
Paint Health Check
Welcome to the Thin Paint Era. By 2018, the factory robots had been calibrated for "maximum efficiency," which is just a fancy way of saying they got real stingy with the spray. These finishes are precise, but they lack the "meat" of older trucks. If you're driving a Canyon or a Savana from this crop, you've likely noticed that the leading edges catch rock chips if you so much as look at a gravel road. We also see the "sunburn" effect on certain 2018 whites and reds where the bond between the layers starts to fail, leading to those infamous peeling sheets. It's a high-tech finish, but it's thin, brittle, and doesn't take kindly to being neglected in the driveway.
Restoration Tip
Since you're dealing with factory layers that are thinner than a diner napkin, build your repairs slowly. When you're filling a chip on that Son Of A Gun Gray or Pull Me Over Red, do not try to "blob" the hole shut in one shot. Modern urethanes shrink as they cure; if you dump too much paint in the chip at once, it'll crater or trap a bubble. Apply two or three whisper-thin layers, letting each one dry fully before the next. It takes more patience, but it's the only way to get a flush finish that won't flake off the next time you hit the car wash.
