Car polishing machines, which one to choose
Car polishers come in all shapes and sizes. You can find information about the most common polishing machines with which to polish a car in this article. A brief explanation of each type.1. Rotating polishing machine (Rotary)

The oldest type of polishing machines.
Their continuous rotating motion provides high power, making them effective for heavy repair jobs. Because they are aggressive, they must be handled by experienced people, amateurs can easily damage car paint with them.
2. Dual action / eccentric polishing machine (Dual Action - eccentric) polishing machines

This type of polisher combines both rotary and oscillating movements, so it can correct paint more safely than other types, while providing sufficient correction ability for most users, from beginner level to professional level detailers.
3. Random orbital polishing machine (Random Orbital)

Orbital polishers, also called random orbital polishers, offer many benefits to users of all skill levels. One of their main advantages is that they mimic the movement involved in manual polishing, greatly reducing the chance of paint damage such as burns or holograms. Therefore, they are very safe even for beginners. In addition to this, orbital polishers are also very versatile as they can be used for different purposes such as sanding and waxing, making them a universal car care tool. Another thing about their movement is that it is random, which gives a smoother finish and also reduces swirl marks. Moreover, these machines are usually lighter and have better ergonomics, which means that users do not tire effectively even if they use them continuously for long periods of time. All in all, you should expect an orbital polisher to be safe and efficient to use with little to no effort as it takes care of everything else automatically while delivering great results - so buy it!
Each type has its own merits depending on how much improvement is required and what skills are required by the user community associated with each particular type.
