Griot's Garage G9 6-inch Random Orbital Polisher

The 1,000-watt motor turns a 9mm orbit at 2,000-6,400 OPM through a gear set 45% stronger than the previous G8 — enough torque to do real paint correction without bogging on the pad's edge. The body weighs 5.

5 pounds and uses a quick-connect 10-foot cord that swaps without tools, which removes the single most common failure point on cheap polishers. Detailing forums show the same pattern repeatedly: when a unit fails — and a small number do, usually inside the first year — Griot's replaces it in under a week, no proof-of-purchase gymnastics.

The lifetime guarantee covers defects in materials and workmanship for the working life of the tool. At $170, the G9 sits between $60 disposable polishers and $400 RUPES units.

The cost per year over 10+ years of weekend detailing is roughly $17 — and the warranty means even a defective one effectively becomes a free replacement.
