Best Cordless car Buffer Buyers’ Guide

Making a purchase decision is not always easy, especially when you are a first-time buyer. Sometimes, you take much time looking for information about the products to purchase. In some cases, you may acquire a product without figuring out some of the critical features and end up getting the complete opposite of what you wanted.

The key features and the reason to buy a given product are vital. I have researched and presented to you some of the critical elements you need to consider when purchasing the best cordless car buffer.

Why Choose Car Buffers 

The acquisition of the cordless car buffer can present the users with several benefits. Even though the use of this outstanding model is also associated with certain drawbacks, its merits outweigh the demerits. The following are the primary advantages of the cordless car buffer models.

  • The buffers help renew the colors of your car and make them look brand new. It is normal that everything usable depreciates and gets old with time. The colors and the luster of the cars fade away with time and makes the vehicles look old. However, through polishing and waxing, your car can seem brand new again. Thus, the cordless car buffer units produce perfect finishes that restore the car’s old look with minimal effort, unlike hand polishing.
  • The buffer helps fill the scratches that your car may develop with time. When you have used your vehicle for some time, it accumulates the scratches on the surface. However, with the buffers, you can effectively eliminate the scratches on the surface and make your car look sleek again. The models, therefore, offer protection to your car against corrosion or rust by water elements that collect in the deep scratches or swirls. This improves the longevity of your car body system.
  • Since you do not cover your car as you use it, the minerals and water can sometimes deposit on the surface of your car, occasionally sticky liquids or materials that may prove a challenge to eliminate. However, with the car buffer, you can efficiently remove the deposits and realize a uniform surface.
  • The polishing and waxing of your car make it look great and sleek and also maintains and enhances its value. It generally helps improve the durability of your car, hence a fantastic tool to have in your collection.
  • The primary role of polishing is to prepare your car’s surface for painting. Polishing helps create a smooth surface that guarantees that the painting process realizes a shiny surface when the polish is applied. The buffer creates a smooth surface, laying a foundation for the painting work.
  • When you get scratches on your car, you will feel it has lost its value. Polishing restores the car’s value and the external appearance that saves you money that you would otherwise use in the future to restore the body of your car.

Disadvantages

  • Using the battery-powered cordless car buffer units may limit you from reaching certain areas, contrary to when an individual uses hand polishing.
  • Since the units are battery-operated, you may be forced to charge them in between polishing as some of the models have batteries with a life of less than one hour.
  • Some units can be costly.

Difference Between Buffer and Polisher

Polishing refers to the utilization of products containing abrasives to even out imperfections. The abrasive process in polishing ensures that the paint is restored and brings out the luster. Conversely, buffering refers to the improvement or modification of the car paint or the clear coat. The utilization of a buffer is aided by using a waxing compound to smooth the target surface.

The below video helps illustrate how you can use a cordless car buffer to remove scratches on your car surface

Below are the top features you should consider before you best cordless car polishers;

Speed Control 

Speed is a significant determinant when deliberating on the best cordless car buffer. Most car buffers have variable speed, while some have uniform speed. When you are due to purchase a car buffer, you need to consider the speed controls as the variable speed allows you to obtain precise and accurate polish and ensures that you protect the tool’s motor against overheating through speed controls. You can effectively regulate the speed when the engine overheats to prevent damages.

The nature of the surface you need to work on also determines the speed you will apply. For instance, superficial scratches do not require much speed to buff. In such a case, a model with variable speed will help you control the speed you use to execute your task.
The speed controls come in varying forms. There is a wide range of speeds that you can choose, with some as low as 300RPM with increments. The increments enable you to select the speed that will suit your needs. For commercial purposes or a professional, you should go for a buffer with a higher number of increments.

Also, you should check the positioning of the speed controls. Some models may have speed dial controls in the hard-to-reach places that will make you strain when executing your work. However, the models with the speed controls at the handles are useful as they present you with the convenience and ease of changing your speed settings to realize the desired speed.

Weight 

The buffer you buy should be lightweight for extended use. Since you will need to lift the machine to work on the car, a heavy model will get you fatigued quickly before executing most of your jobs. 

Consider buying the model with the least weight and that with a compact design. The lightweight models will help enhance your maneuverability. An example of a lightweight and compact model you may consider is the PORTER-CABLE Variable Speed Polisher. With only a weight of 5.5lbs, this unit will guarantee you a longer run time with minimal fatigue to your hands.

Power

When dealing with numerous cars as a mechanic, power is essential when shopping for a cordless car buffer. A mechanic or a garage owner dealing in different cars would go for a powerful car buffer. Some models boost up to 75 W of power with 120V battery capacity. Such buffers would be perfect for cars in bad conditions with swirl and scratches that requires maximum attention. One of the most powerful models you would find at amazon.com is Chemical Guys BUF_503X TORQX Random PolisherThe unit has a 120V battery and boosts up to 120W, ensuring a longer runtime from a single charge.

Conversely, consider a car polisher with variable speed control if you need the best car buffer for micro-scratches with the car’s exterior in good shape. The type would help you manipulate the speed depending on the nature of the scratches you intend to work on.

Vibration 

Comfort and accuracy are essential elements when using a car buffer. The model you choose should provide you with the comfort that you need for extended use.

The car buffers often vibrate when in use. However, when the vibration is too much, it will compromise the accuracy and comfortability. I recommend that when choosing a model for your car, go for the one with the least vibrations. 

Functionality

The functionality of a cordless car buffer must be determined before purchase. Numerous organizations have taken pride in manufacturing the most efficient and easy-to-use car buffer models, but the functionality of these units must be kept in check before purchase.
You may consider asking the professional mechanics about the different brands or checking on the reviews from the first-hand users. You should not invest in a polisher that will only damage your car’s surface or would not realize your mission of purchase, not providing you with the value of your money.

Hand Control

The tool you choose should give you the comfort you need to ensure that you have all elements that come with the nature of work. You should select the model with a secure handle grip since this will help you get accurate results and comfort for extended use.

Also, you should check the position of the speed control dial on the handgrip. The positioning of the controls helps you quickly and conveniently vary the speed without the hassle of reaching the dial when located far from your handle. Go for the models with a rubber grip that will provide you with a firm grip and reduce strain in the hands.

Buffer type

There are two primary types of the buffer based on the orbital action; the rotational and the random orbital. I recommend that when making the purchase, you should go for the model with random orbital since they help reduce defects as well as prevent any swirling and streaking to realize accurate polish.

Price

Price is another vital consideration before purchasing the best cordless buffer polisher. With the other desirable features, you may get a perfect cordless buffer model right for you within your budget.

Frequently Asked Questions

Can You Use an Orbital Sander for Polishing?

An orbital sander refers to a handheld tool used to both polish and sand different surfaces. Its polishing mechanism involves moving in a single direction circularly and using a waxed pad to polish and buffer a car’s surface. Thus, the tool can perfectly execute the polishing job. However, you must take note of the variable speed settings and ensure you have integrated the correct speed for the polishing.

What Causes Swirls when Buffing?

When buffing, the swirls produced on your car’s surface can be so irritating, and most people always strive to seek their root causes. The swirls that result from buffing start to develop from the micro-scratches. These scratches result from even the tiniest dust and dirt on the buffing pad. When you use a buffing pad that was dropped on the floor or if you fail to clean a buffing pad used on another vehicle, the pad becomes more abrasive and will cause swirls. 

Thus, to prevent the swirls when buffing, ensure that the buffing pads are spotlessly clean before use as even the microscopic dirt or dust would cause the micro-scratches that develop to swirls when the pad is used.

How do you buff out scratches?

Toothpaste is handy when it comes to buffing out scratches and scuffs. However, this method is ideal when the scratches have not completely penetrated through the clear coat of your car’s paint. All you need is a damp, soft cloth on your hand, smear some toothpaste on the affected parts and wipe the scratches and scuffs off with ease. 

What is the difference between waxing and polishing a car?

Waxing protects and improves a car’s paint coating. Wax on cars is primarily used after cleaning and polishing to ensure your car’s paintwork shines. Unlike polishing, where a fine layer of paint is removed, car wax is used to smoothen over the top of the paint. Thus, polishing is used to remove the existing paint while waxing smoothens the paint.

Are cordless car polishers any good?

The cordless car polishers are perfect for restoring your car’s original look. In the detailing industry, these units have played exemplary roles in bringing that shinny to feel in cars and making them look new. These units provide sufficient speed rotation and torque, similar to their corded counterparts. This makes them ideal, considering that they are portable and do not require the wall sockets to operate as they are battery-powered

Conclusion

Polishing a car is undoubtedly the best moment, especially when irritated with the scratches, swirls, and mineral and water deposits that have made it look old and out of fashion. Worst still, choosing the best cordless buffer tool to buff your vehicles is also a monotonous task, and you may end up choosing a tool that does not meet your desired objectives or is challenging to operate. 

I have researched the top features you need to consider when buying a car buffer to help you make the best purchase decision. I have also listed the best cordless car buffers in the market today and hope it will help you make a better decision. Among the top units, you may consider my top pick, DEWALT Buffer/Polisher, Variable Speed, Soft Start, 7-Inch/9-Inch. This unit not only boasts an impressive speed of up to 3500rpm but also has a powerful Lithium-ion battery rated 12.0Ah that will provide you with an extended runtime just from a single charge.
