Random orbital polishers, also known as dual-action polishers, are popular among automotive enthusiasts and professionals for their versatility and ease of use. These polishers feature a dual-action motion that oscillates and rotates the polishing pad simultaneously. This movement helps to minimize the risk of paint damage, such as burning or holograms, while still effectively correcting imperfections and enhancing the paint's gloss.

Rotary polishers utilize a direct drive spinning motion, making them more aggressive than random orbital polishers. They can remove deeper scratches and imperfections but require more skill and experience to use safely. Rotary polishers are often preferred for professional detailing or paint correction work where more aggressive correction is needed.
