Agreed. first owner of my fatboy had something strapped to the rear fender, clearcoat is all effed up right between the rear of the seat and the license plate bracket. I have a luggage rack that takes about 2 minutes to attach to the sissy bar, that's the way to go.On a luggage rack. Mounting it on the paint will result in paint damage due to the material rubbing the paint.
You *could* mount it on a soft rubber pad, but I prefer zero paint contact.
