hi...what you need is autoglym paint restore from a trade supplier i.e. an autoglym agent just look on the autoglym site and find a mobile sales agent near you. but use a low cut, this will remove the swirls or most of them with out using a machine polish or G3 cutting cream (trade/paint use ) then polish using autoglym resin which has a finer cut and finally use carnouba wax which is mainly used on black cars giving a deep shine and lasts for months but for best results use a couple of coats. i am autoglym trained after i owned a valeting centre !
