The Flex 3401VRG 5-inch Polisher is a legendary forced-rotation machine that combines the correction power of a rotary with the safer, more controlled feel of a dual-action polisher. Its positive-drive design keeps the pad rotating consistently even under pressure, letting you cut through swirls, oxidation, and defects efficiently while covering ground faster than a standard random orbital. This forced rotation gives you predictable, powerful correction with reduced risk of the pad stalling, making it a favorite among professionals who want serious results with confidence. Well-balanced and durable, it's built to handle demanding correction work session after session. Pair it with your favorite RCP cutting and polishing pads plus quality compounds and polishes to bring dull, marred paint back to a deep, glossy, professional finish.
