No, it did not come from the factory that way. And yes, the car got a full paint correction and polish before the Opti-Coating . . . but that was just a week after we got the car, and these scuffs weren't there.
Over the past week or so, I had noticed a lot of dust buildup on the rear bumper. All our cars pick up dust on top of their rear bumpers from some construction and road work out our way, but the Lucid was accumulating noticeably more, probably due to the airflow characteristics over that part of the car. I'm talking a light coating of gritty dust, though, nothing that built up any kind of crust. When I was drying the car after washing it, I pulled the edge of the towel under the trunk lid in the scuffed spot to see if it would clear, and it did. This means the parts are coming into contact due to some deformation that happens when driving, and the dust on the bumper must have been working as an abrasive.
I have not yet taken this car shopping, to an airport, or done anything else that causes me to use the trunk. Other than washing the car today, I doubt if I have opened the trunk more than a couple of times since we've had the car, and that was just to show some people the space.
