My brother who is ''fanatical'' about his Porsche 911 Carrera (black on black oyster paint , the most expensive color Porsche sells) told me years ago that most if not all pro detailers use a synthetic polish called Nufinish on all expensive paint jobs . This polish was also Consumer Reports winner of over 50 different polish compounds tested . This polish protected paint better than all the competition . This polish is not a ''cleaner'' polish though , so if you have any oxidized paint on your car you need a cleaner before you ''seal' the finish . Natural ''wax'' based polishes do not protect near as well , but the bad part about them is that they ''yellow'' with age even the expensive ones . I would never use them ever ! Nufinish only for my Benz ! 1989 420 SEL looks ''show room''great , the finish is a mirror .
