My brother-in-law asked me if I could buff his car, hoping that I could work some magic on his 12 yr. old paint job. The paint isn't all that bad on the sides, but on the top it's pretty dull looking. The buffer I have is a 10" orbital which is set to 2800 rpm only. Is there anything I can do to get the top looking shiny again? I know I'm limited with this type of buffer, but would a combination of rubbing compound, polish, then wax even make a difference to paint in this condition? Any help would be great. Thanks.
