Personally i've used G3 and Meguiars - the Meguiars correction compound on their Microfibre pads used in conjuntion with a DA polisher produces an excellent finish, it also seems more effective than the meg's red foam pad and their own 205 compound and doesnt require any water therefore alot less messy! http://www.cleanyourcar.co.uk/meguiars-da-microfiber-correction-compound/prod_962.html
