In car beauty and maintenance, the correct sequence should be polishing first and then waxing. The main function of polishing is to remove the oxide layer, fine scratches, and stubborn stains from the car's paint surface, restoring its smoothness and creating a better foundation for subsequent wax adhesion. Polishing requires professional abrasives used with a polishing machine or manual operation. Products with varying cutting strengths should be selected based on the paint condition. During operation, maintain consistent pressure and avoid generating excessive heat that could damage the paint. After polishing, thoroughly clean all residues from the paint surface and ensure it is dust-free before waxing. For wax application, use high-quality natural carnauba wax or synthetic polymer wax, applying a thin layer in circular motions. Once the wax hazes, immediately buff it in straight lines using a microfiber cloth. Note that excessive polishing will diminish the clear coat thickness—professional polishing is generally recommended no more than twice annually, while waxing can be maintained every 2-3 months. New vehicles don't require polishing within the first six months but can use pure protective wax without abrasives. When selecting wax, metallic paint vehicles benefit from wax containing UV absorbers, while dark-colored paints may use gloss-enhancing wax for better visual results.
