I like my Makita 9227.
"Makita Rotary Polisher: Even the daily grind of heavy paint removal will not wear out this durable polisher. The #9227 Makita, Variable Speed Rotary Polisher is also ideal for slow polishing. It's electronic speed control maintains constant speed with a surprising amount of pressure.
This is the machine you'll need for serious paint flaws, Fiberglass restoration, or metal polishing. It does the dirty work, and makes it seem easy.
The Makita is a professional quality high-speed and is a favorite of our pros because it seldom has down-time. It has a large, wrap-around handle which allows the user to easily grasp at any angle, at any speed. You can use the variable speed dial for maximum control, or you can choose the convenient trigger for ultimate precision and safety. The trigger is probably its most popular feature."
