Wet sand buffing and polish is a crucial step in car detailing that can significantly enhance the overall appearance of a vehicle. This process involves using a fine-grit sandpaper and water to remove imperfections and scratches from the car's surface. After the sanding is complete, a polishing compound is applied to the surface to restore its shine and luster. This technique is particularly useful for removing deep scratches, water spots, and other blemishes that cannot be removed through regular washing and waxing. When done correctly, wet sand buffing and polish can make a car look like new again.
