Waxing
Waxing protects the paintwork. You will need to re-wax the vehicle with a good hard wax if water no longer clearly forms small drops and runs off the paintwork when it is clean.
Even if a wax solution is used regularly in the car wash, Volkswagen recommends protecting the paint with a coat of hard wax at least twice a year.
Polishing
Polishing is only necessary if the paint has lost its shine, and the gloss cannot be brought back by applying wax.
The car must be waxed after polishing if the polish used does not contain wax compounds to seal the paint.
