This is the polisher to purchase if you are serious about doing a professional polishing job. I restored a 1983 Mercedes 380 SL and buffed the paint last year with a cheaper machine that burned the paint. This Makita was easy to use and made a quick job of buffing the entire car. It was very comfortable in hand, no straining. I would recommend a soft sponge head from NAPA for around $28. This type of head makes it nearly impossible to burn the paint. The polishing head even on the slowest setting did not bog down when pressure was applied assuring you get an even polishing job without burn.
