For the removal of defects in your cars paint finish, one of the options is the use of polishing machines. Usually either Dual Action, or Rotary. The Dual Action is safer for the beginner to car detailing, the Rotary for the more advanced detailer. Either way, great care is needed for this aspect of car cleaning. A few practice panels would be a good idea! The correct grade of car polish is also necessary, as is a good set of polishing pads.
