Our take on the Meguiar's MT300 Dual Action Polisher

The Meguiar's MT300 is a corded dual-action polisher built for compounding, polishing and waxing paint on cars, RVs and boats. Its 540-watt motor runs 3,000 to 7,500 orbits per minute with a thumb dial, and Digital Torque Management adjusts torque to hold speed under load. A billet counterweight on a multi-bearing design keeps vibration down, and the removable multi-position D handle adds control. It is a pro-grade tool aimed at detailers and paint shops rather than casual weekend waxers.
