Griot's Garage G21 Long Throw Orbital 6 Polisher Engineered with the goal of professional-level paint correction in mind, the Griot's Garage Long Throw G21 Polisher offers a potent combination of power, pad rotation and precision. This impressive tool marries Griot's robust 1,100-watt big block motor with a 6 backing plate and a massive 21mm throw pattern. In comparison to the smaller Griot's Garage G9 Polisher, the G21 retains the same ergonomic design but boasts a 20 larger housing, a 22 power boost and a maximum speed of 4,500 orbits per minute. Exclusive to G21 (and G15) models, the innovative fan-integrated backing plate and billet counter balancer are engineered to mitigate vibration - especially when using heavier microfiber buffing pads (versus foam). Note : When converted to a 5 backing plate and fitted with a Boss Microfiber Fast Cutting Pad, the G21 is Griot's most aggressive paint correcting combination. It should be noted that long-throw polishers are not ideally suited for application of waxes and sealants. The extended throw tends to cure the wax unevenly (with the exception of Griot's Boss Finishing Sealant - which is designed to comply with the heat cycling of long-throw orbits). The G8 or G9 Polare most suitable for wax application.
