Light scratch or scuff removal
Do it by hand, with three items. Use a rag or t-shirt, a polishing compound(fine), and a wax(no grit). First, rub the scratch out with the light grit polish, then add the wax onto the same spot of the rag, and rub it again to remove the polish scratches. Finish it by rubbing again with just the wax.
This removes some clearcoat, but on the side it should be fine. I have removed many dozens of scratches, lately from my mail vehicle. I had new paint, so I knew that I had thick clear coat. I used to detail cars, so I know what I'm talking about.
You can use a machine, but that removes paint from a large area, not just along the narrow area of the scratch. It is relatively easy by hand, and when finished, and done right, it will be completely unnoticeable.
Good luck,
