a paint stick will work, or they make blocks just for that. get a soft block that will follow the contour of the body. Sand until the shine is gone, use a lot of water, i like using a spray bottle; a garden house make a mess, and a bucket gets dirty. If you don't have much wax on the paint, it doesn't take very much sanding to take off 1 mil of the clear coat. Depending on the scuffs, they probably aren't very deep. Then buff to shine, careful not to burn through the clear, especially on the body lines, corners, edges of panels, etc.
