Hand polishing/waxing vs. machine polishing/waxing, which should I use?

Both hand and machine polishing work great on cars with minor paint defects. We recommend you use a buffer if you have a large amount of swirls or many visible paint defects. Another reason to use a buffer is speed. Large SUV's, vans and trucks can be very time consuming to clean and wax and a buffer can make these jobs go a lot faster.
