DA polisher (dual-action)
A DA polisher, or dual-action polisher, is a machine polisher that combines rotation with random orbital motion to safely polish car paint without burning the clear coat.
What it means
Machine polishers come in two main types. A rotary polisher spins the pad in one direction at high speed, which generates heat fast and is powerful in skilled hands but easy to burn through clear coat with. A DA polisher combines rotation with a wider random orbit, so the pad spins and wobbles at the same time. The wobble dissipates heat and randomises the contact path, which makes the tool dramatically safer for paint and accessible to a wider range of operators without sacrificing too much correction speed. Modern long-throw DAs (12mm to 21mm orbit) are powerful enough for professional-grade single-stage paint correction on most paint systems. Pad choice (cutting, polishing, finishing) and compound choice (cutting compound, polish, finishing polish) are matched to the level of correction needed and the paint hardness. Used right, a DA polisher is the modern standard for safe, repeatable paint correction.
Why it matters in Singapore
Singapore paint systems are typical of modern cars: relatively thin clear coats with fairly hard formulations. A rotary polisher in inexperienced hands can cut through the clear coat in seconds. A long-throw DA polisher, with the right pad and compound, gives a margin of safety that protects the customer's paint while still removing swirl marks and oxidation effectively.
How Revol Carz handles this
Revol Carz uses long-throw DA polishers as the primary machine for paint correction and grooming work. Pad and compound choice are matched per panel based on paint depth readings and the defect being corrected.
