And as if by magic here i am, well Murdo you are right a mashine polish can normaly get most fine scratches out and as the Audi has very hard paint some times thats all you need,i work in a high volume refurb centre working on new and 6month old Audi's and we never use any of the scratch remove stuff they just don't work, they are full of fillers so all they do is fill the scratch, if they did work we would use truck loads of the stuff ( as a company we do some 500+ cars a week). Keez where abouts in the country are you ?
