Yeah, buffer trails are just awful. This damage is mainly inflicted at the dealership as a quick prep for a sale by someone who has no idea how to use a machine polisher. They're not too hard to get rid of if you have a dual action polisher, or know someone with DA or rotary. You can correct by hand but it will take a bit of effort and time. If you want to go down that route, I'd highly recommend G-Techniq P1 and a German applicator pad as they're great for correcting by hand.
