Basically, polish is an abrasive and only needs to be used to sort out paint problems. New paint on bodywork or wheels should be waxed rather than polished. The wax will seal, smooth and condition the paint. It will make it repel water UV light and brake dust. Its really worth doing with a new car, particularly on the wheels.Black always looks good, shame is a git to keep clean, any dirt shows up immediately! Whats the deal with waxing instead of polishing?
