Car Polishing Machines and the Difference Between Rotary, Dual Action & Orbital


Author: Rob Mobberley

With the recent launch of the new Dodo Juice Spin Doctor Rotary car polisher, we have had many enquiries about how suitable Rotary car polishing machines are for first time users and what the main differences are between Rotary, Dual Action and Orbital car polishers.

Rotary Polishers

The motor on these machines directly drives the polishing head that fixes directly to the backing plate onto which you fix your cutting, polishing or finishing pad. This means all the power, and there can be a vast amount of it, is directly driving the rotation of the machine down onto and across your paintwork – too much pressure and you can quickly burn through your paintwork.

However the upside is that if you are seeking to do paint correction the Rotary is more suited to this type of work as it will allow you to take the paint layers down further and quicker than either a Dual Action or Orbital. Many professional detailers use a rotary polishing machine for both speed and where required for full paint correction details. However many will be the first to admit they started out with a Dual Action such as the original Porter Cables before moving onto the Rotary car polishing machines.

Dual Action Polishers

The Dual Action polishing machine is ideally suited to light scratch and swirl removal and deep shine buffing – it would not be the ideal choice for the removal of deeper scratches where your finger nail “jarrs” when passed over the scratch (the finger nail test).

Orbital Buffers

 These tend to have larger heads and dual handles that allow the machine to be pressed onto the paintwork. The also tend to work at lower speeds and have a single “jiggle” movement rather than spin. They are ideal for applying product deep into the paintwork over a larger area and removing same (using different bonnets). They are however not as versatile as the Dual Action polishers, which will allow the use of different size plates and pads and work at higher speeds, whilst being more user friendly than a Rotary.

The Dual Action as by its name combines two actions, one the rotating of the plate holding your pad and the other is the oscillation of the spindle. An easier way to understand this is comparing it to the action of the earth – which itself spins, whist at the same time orbits, or oscillates around the sun.

The motor on these machines directly drives the polishing head that fixes directly to the backing plate onto which you fix your cutting, polishing or finishing pad. This means all the power, and there can be a vast amount of it, is directly driving the rotation of the machine down onto and across your paintwork – too much pressure and you can quickly burn through your paintwork.

Which Polishing Machine Should I Choose?

The choice of machine really depends on what you want to achieve and your level of confidence (experience). The beauty of the new Dodo Juice machine is both the introduction of digital speed control and the lighter weight. The speed on this new machine can be set in 100 rpm increments from 1000 rpm to 3000 rpm, making it more user friendly than traditional rotary machines. It does however still need to be treated with respect.

The Dual Action Car Polisher (DA) machines whilst not being equal to a rotary when it comes to paint rectification work, will produce excellent, professional looking results with the added benefit that it is much harder to do any serious damage to your paintwork than it is with a rotary. And lastly if you are seeking simply to save time and cover large areas the traditional dual handled orbital buffer may be the ideal choice.

    Dodo Juice Machine takes my vote. One of the positive point is that it is the lightest weight in its category and speed can be adjusted easily. It gribs well in hand and less chance of slipping.

    I have one, and it is very reliable and long lasting. It consume less power and gribs very easily. The size of the pad is also very reasonable…remember. bigger pad tends to slip and are not good while doing the corners.
