Car Polisher Buying Guide

The process of polishing can be intimidating and is often misunderstood. Waxing and polishing are two different concepts because waxing simply protects the paint whereas polishing is done in order to break down and remove defects.

Polishing your car by hand can still have excellent results by using the best car polish for your specific paintwork. However, you will never get the same results as you would with one of the best car polishers recommended above. Once you have successfully removed all defects, you would then go ahead and apply a protective wax to your paintwork to protect any further defects appearing.

The Process of Polishing Your Paintwork

Properly polishing the cars paintwork requires you either to round the edges of the scratches or buff away an extremely thin layer of paint that eliminates the visibility of the imperfection on the surface.

The removal of paint requires a very delicate touch, especially since the amount of paint that is removed will greatly depend on the amount of force that is applied when using the car polisher. If you are new to polishing with a machine, we highly recommend trialing it out on an older vehicle that you are not that worried about with regards to the paintwork.

The spinning pads and the cloths attached to them are capable of removing blemishes and scratches with a cutting compound as well as applying waxes.

Types of Car Buffers

As you can imagine, there are many different types of car polisher machines but the two main types include a dual action polisher (also known as a DA polisher) and a rotary polisher. Both have their own benefits and drawbacks and are suited towards certain applications.

The rotary car polishers function on a single axis where the head spins in a regular circular motion. This results in the build up of heat and friction that allows you to work a cutting compound into the paintwork.

Dual action polishers that are often referred to as DA polishers spin in two different motions (hence the term dual action). In short, the head spins in a concentric circular motion on a spindle, which results in a wider circular motion. This type of circular motion prevent excess build up of heat or friction upon the same surface, which prevents any damage to the paintwork.

Advanced models of dual action polishers are equipped with a positive drive action. They still allow the power tool to wobble in order to disperse heat and friction, but the wobble movement is actually purposefully driven as opposed to being the random result of oscillation.

Dual Action vs Rotary

Rotary vs Dual Action Buffer

When it comes to choosing between the two different types of car polisher machines, there is various pros and cons for each. Rotary machines are normally cheaper and can be used for light to heavy paint correction work.

However, in the wrong hands, there is potential to cause damage to your paintwork resulting in swirl marks, hazing and other defects.

Dual action car polisher machines therefore are great for beginners that want to carry out light to moderate paint correction work. However, you may struggle with heavy duty correction work.

Buffer Machine Weight & Ease of Use

One of the most significant considerations to make regarding a polishing machine is the weight. This is due to the fact you must be able to easily control and direct the tool in order to effectively work the cutting compound into the paintwork.

For beginners, the lighter polisher machine is highly recommended as there will be less weight being pressed against the paintwork. This will reduce the heat and friction and will prevent the risk of causing any damage.

The weight of the car polisher machine is one of many factors that define how easy the tool is to use. Of course, there are many other factors such as the ease of switching between the speed settings, switching between the pads, hand control aids and much more.

Common Mistakes Car Buffing Mistakes

Using the wrong technique when polishing your car, you can cause expensive damage to your paintwork. However, there are many easily avoidable mistakes that you should avoid in order to preserve your cars paintwork and these include:

  • Using the incorrect buffing pad or cutting compound
  • Buffing one area too hard or for too long
  • Setting the speed/RPM too high to begin with
  • Not using tape to mask off plastics and other components
  • Using too much or too little cutting compound
  • Not fully cleaning the vehicle beforehand
  • Using a dirty buffing pad
  • … and much more

Technique is key to ensuring that you are actually correcting the paintwork and not making it worse. We highly recommend that you watch various video tutorials for helpful tips. Below are some tips to help you get started and safely polish your car.

Preparing the Paintwork

Due to the speed at which the polisher machine turns the buffing pad, it can be enough to cause damage. This can include causing permanent marks to plastics, headlights and other components. Therefore, before using any polisher regardless if it is a rotary or DA polisher, we highly recommend using masking tape around certain areas. In the below photo we taped up the brake lights, plastics and edges of the convertible roof. To ensure that the sun does not dry out the cutting compound, a carport canopy is also used to block the sun, which is also highly recommended.

Conclusion

For those who are looking for a car polisher, there are multiple options to choose from. From car polishers for beginners to those that perform detailing tasks on a daily basis. However, you can have the best car polisher but if you do not have the technique to match, you will not be able to get the results that you desire.

All of our recommendations are suited for a range of applications but we highly recommend you test on an old car beforehand. Once you have perfected your technique and tested a range of rubbing compounds, you should feel confident enough to correct the paint on your pride and joy.
