I have a 1998 Ming Blue S4 and the paintwork is far from perfect. Pretty much every panel seems to have swirls that are very visible when it's cleaned up. Some look really bad, i'd be terrified to see what they are like under the lights the detailers use! Can anyone recommend some products and techniques which will help clear the swirls up on a budget of less than £50, or am I being a dreamer? Any info would be greatly appreciated.
