There are three stages to beautifying a car. First take off any contaminants that have got on to the car's paintwork using a car washing solution. After which the paintwork can be "polished". This is the second stage and may be accomplished by hand or, in some cases, by using a rotary polisher. Polishing a car removes a microscopic layer of paint, this is the stage that gives the beautiful finish. Only after the first two stages have been completed should a wax be applied. It is important to understand that the wax is not polish and no paint is removed. Wax protects the finish you have achieved. A well waxed car may not need to be polished again for some considerable time. Just washed and then waxed.
