I have a 2002 MB C240 that has recessed door areas for each door handle. There are fine scratches in each recess which I assume are from fingers/fingernails raking tha area when the doors are opened. What is the best/easiest way to remove these scratches and what would be the best product to use? I have gone over them in the past with a fine polish that I bought from the supply house where I get my detailing supplies, but I couldn't remove them all the way.
