Dual action polishers are excellent tools for improving the appearance of automotive paint. The motion of the pad is described as dual action, hence the name of these polishers. The pad rotates and orbits. The constant, off-center motion keeps heat from building up under the pad. Damaging the paint is extremely unlikely with a DA polisher. For this reason, many beginners start with a dual action polisher.
Dual action polishers have a place in the garages of experienced detailers, too. The random orbital motion is excellent at applying waxes, paint sealants, glazes, and fine polishes. DA polishers are also called random orbital polishers. Choose from polishers by Porter Cable, FLEX, Meguiars, and Griot's Garage.
