I use a product called Plexus, It was originally used in aviation for fighter canopies. it is an aerosol spray polish and it is absolutely the best thing i have used on my Busa. The price has gone up on it in the last year or so, but it goes a long way. it wad 26.00 for 13oz. can. it fills in micro scratches and makes paint, chrome and windscreen look amazing and also makes cleaning easier..most cycle shops carry it here but it is available online as well.
