We are often asked if polishing paint is better done by hand or machine and the answer is always by machine. The reason is simple, you just can’t get the results by hand that you can achieve by machine. Your hand is not capable of doing the work a machine can do when it comes to paint polishing or even maintaining your finish. It is humanly impossible to osculate your hand evenly over the entire surface of your car at a rate of 2,500-6,800 times per minute.
