Remember how we had explained the irony of rotary action polishers being cheap but hostile for beginners, whereas the expensive dual action counterparts are practically idiot-proof? Well, Meguiar’s dual-action polisher combines the best of both worlds by borrowing the ease of a dual-action polisher with the cost-effectiveness of a drill attachment.

Although it’s as expensive as the cheapest rotary polishers at $39, this drill attachment eliminates the steep learning curve associated with cheaper polishing attachments.

The dual-action nature of Meguiar’s polishing solution makes it easy to achieve a cleaner surface finish by reducing the risk of hologramming, buffer trails, swirl marks, and other detailing defects. We don’t recommend springing for this drill attachment if all you wish to do is buff out scratches or restore headlights. However, this is well worth the extra cash if you plan on undertaking larger polishing and buffing tasks.

Unlike cheaper polishing attachments, Meguiar’s dual-action polisher cannot be paired with any old cordless drill. That’s because the mechanism responsible for generating the multi-axis rotary movement typical of dual-action systems does so with the help of internal gears. This, however, comes at the cost of transmission losses. Although Meguiar’s recommends corded drills, you can still use it with a fairly powerful and efficient cordless drill, preferably those sporting brushless motors. Anything less, and you’re sacrificing polishing power.
