90% of my vehicles have been black. If you work fast and not let the polish dry you can apply a polishing compound and remove with a buffer. A standard low speed orbital will be fine again if you move properly. Best product I've ever used was Turtle Wax black box for $20. It made what a seller considered "needs a paint job" on an 04 Mustang Gt I picked up into a glass black damn near perfect corrected paint. It was a lot of fast paced work but I couldn't imagine a product would work like that. I'm on the east coast so when the weather breaks I'm doing my 06 Expedition in the same manner and will be sure to post results. It corrected hard water spots, swirls, scratches, and even some chips. Only works on black cars tho.
