Where on a 2018 Chevy Trax is the paint ID number? I bumped into the rear, driver side panel, behind the passenger door and the paint gouged. I'd like to get a paint pen to cover it. However, I must say the paint job on this car seems remarkably fragile. Admittedly my kids closed the back doors on the seat buckle a few times and each time it gouged in the door jam. I've had the same thing done on many other cars and the damage was negligible. Not on my Trax, sadly.
