The double-action polisher is an eccentric rotation polisher. This means that the pad or backing plate does not only rotate on itself but also oscillates. This results in a random orbiting motion that avoids the burns often caused by rotary polishers. A dual-action polisher is the most commonly used machine for polishing all vehicles and all types of paint. The random orbital nature of a Dual Action polisher means that it generates much less heat than a rotary polisher. It’s a gentler tool, so the correction job usually takes longer. However, it’s also safer to use and easier to learn, which is ideal for beginners. Ronix dual-action polisher can be used for most polishing or buffing jobs. Whether you want to enhance the aged and dull paint on your vehicle, or if there are scratches in the paint you want to remove. With Ronix 8309, you can repair paint, and small or large imperfections like scratches and bring a beautiful shine to your vehicle’s finish.
