I have a 2020 LRMY with the Pearl White Multicoat paint. There are three layers to the Pearl White Multicoat, not counting the primer. The base coat is flat white. The mid coat is semi-milky with added metallic flakes. The top layer is a clear glossy finish. As I am in the process of repairing a few scratches, down to the bare metal, I can say that the paint on the body panels of the Model Y is incredibly thin (thinner than an egg shell.) Even with a computer controlled paint sprayer it would be difficult to paint the bumper and have it match the body panels exactly.
