You need a good buffer like auto body guys use that has variable speed and can turn some good revs. Go to a auto paint supplier and get the 3m heavy wool pads (2), not the lite ones. Also while your there buy a pad cleaner, it fluffs and cleans the pad but doesn't ruin it like a screwdriver will. Get some 3m super duty rubbing compound and some finishing compound. Use a different pad for each. Test an area and use a liberal amount of compound at high speed, careful around ridges and corners. If this doesn't take them out totally then carefully wet sand first with 600 or higher and then rub it with both compounds. Wax it last with the buffer and some collinite fleetwax. This should get them out
