Benefits of Dual-Action Polishers
- Remove minor scratches and swirls. A dual-action polisher can be used to buff out minor scratches and swirls to improve the appearance of your vehicle. It will also make the paintwork look more lustrous.
- Safe for paintwork. When pressed down on a surface, a dual-action polisher stops spinning and starts to vibrate. The vibration helps to dissipate heat so that the paintwork doesn’t get damaged. This is a safety mechanism that sets it apart from other car polishers and lets beginners know that they need to move to another spot or slightly lift the polisher.
- User-friendly. Most dual-action polishers have a simple design that’s user-friendly for both DIYers and professionals. You only need to use the right buffing pad, power the device, adjust the speed, and guide it on the surface while keeping a firm hold on the handle.
Types of Polishers
Dual-action, or otherwise known as a random orbital polisher, is a motor-driven machine that oscillates and rotates to create a double-action when polishing, sanding, waxing, or adding paint to a surface. It’s designed to mimic the circular hand motion you make when polishing a surface. It’s easy and safe to use since it’s designed to vibrate to keep heat from penetrating and damaging the paintwork.
Rotary polishers only have a single polishing/buffing head that rotates on the surface to perform deep paint correction. Since the polishing head is continuously attached to the surface, heat builds up, making it possible to buff out or refill deep paint scratches. They are best used by professional detailers who know how to control the machine to avoid further damage.

Dual-Action Polisher Pricing
- Under $150: Power tools within this price range are best used for home maintenance projects. Professionals may find them a bit underpowered since most have a low RPM rating. Also, most come with a small buffing pad that’s less than 6 inches, meaning that it may take longer to work on several vehicles.
- $150 and up: Professional detailers should look for dual-action polishers within this price point — they have a higher speed rating and can handle heavy-duty detailing tasks. However, ensure that you aren’t just paying for a brand name and that the reviews match the tool's price.
A power tool’s motor speed is rated in revolutions per minute (RPM) or orbits per minute (OPM). The motor speed helps determine the detailing projects you can take on. For instance, a power tool that’s rated above 3,000 RPM can handle heavy-duty projects such as buffing out deep scratches on the bodywork. Ideally, you should choose a tool with variable speed settings you can adjust depending on the task at hand.
Since you will be using the polisher for lengthy periods, it’s important that it feels comfortable in your hands. For this reason, choose a unit with an ergonomically shaped body that contours to the shape of your hand. As a bonus, it should come with an extra side handle or D-handle that helps reduce hand fatigue.
All detailing power tools should come with several safety features that keep the machine from going out of control. If not, it may end up damaging your paintwork. Therefore, prioritize tools with an automatic shutdown that kicks in when the tool is used incorrectly or a speed lock feature that keeps the motor from increasing or decreasing the speed.
- Vibration. Dual-action polishers typically vibrate as part of the buffing process. However, you don’t want a polisher that vibrates since it can strain your hand and lead to inaccurate finishes. Before buying a polisher, check the user reviews to see if excessive vibration is a big issue with the machine.
- Corded vs. Cordless. Most random orbital polishers on the market have a corded design and need to be constantly plugged in to work. However, you may want more freedom to move around without cables tagging behind as you work. In that case, you can go for a cordless design that runs on a rechargeable lithium-ion battery.
Best Dual-Action Polisher Reviews & Recommendations 2021
- Test the polisher on a different surface before using it on your vehicle. This way, you can determine if it's safe for your paintwork, and you can also learn how to control the speed.
- Polish your vehicle by dividing it into sections. Use old newspapers to cover the sections that are unpolished and strip them off them as you go. This will get a more even coat without unpolished sections.
- Be sure to work in a well-lit room so that you can see the results of your work. It will also be easier to avoid damaging the buffing pad on your vehicle's sharp edges or trims.
- The easiest way to tell if you can remove the scratch yourself is by running your fingernail on the scratch. If it gets caught on the scratch, it means that the scratch is too deep and you will have a hard time removing it. In that case, you should consider asking for a professional's help.
Q: What is a dual-action polisher?
A dual-action polisher is a power tool that's used to smoothen out your vehicle's bodywork and for applying wax. It combines a circular and spinning action, which creates a double or dual action. It also vibrates while it spins so that it doesn’t burn through the paint.
Q: What is the best dual-action polisher?
Though we picked the Dewalt Buffer/Polisher as the best overall dual action polisher, finding the best polisher is subjective depending on the functions you are looking for. You may prefer a waxer/polisher combo over a sander-polisher. Therefore, any of the polishers on our review could be the best for you.
Q: Can a dual-action polisher remove scratches?
Yes, it can. The repetitive spinning action can help smoothen out minor scratches and fill it with automotive wax and paint. However, it doesn’t produce enough heat to remove deep scratches on the paintwork.
Admittedly, the Dewalt Buffer/Polisher is the best dual-action polisher because it’s easy to use, energy-efficient, and versatile enough to offer a wide range of speed settings to accommodate different detailing projects. If you are looking for a more budget-friendly option, consider the WEN Waxer/Polisher.
