NOT ALL CAR POLISHERS ARE THE SAME
We have all heard the horror stories of people burning their paint or creating horrendous swirl marks by machine and because of this people fear polishing their paint by machine. These stories are usually true stories but they DO NOT involve the dual action polishers like the Porter Cable 7424 XP Car Polisher.
Paint damage by machine is created by rotary buffers, which spin at a high rate of speed, and in the hands of the inexperienced detailer can create severe paint damage. Rotary buffers are for the trained professionals who have experience and need to remove severe defects prior to polishing with a dual action polisher.
WHAT'S THE DIFFERENCE IN CAR POLISHERS?
The car polishers found in your local auto parts store work like a jitter bug sander. They lack the power and versatility necessary to properly polish modern clear coat paint finishes and do little more than apply your car wax. These machines, like the one pictured above, operate at a single speed of less than 2,200 OPM. This is very common on all machines in this configuration.
Dual-Action car polishers operate by orbiting the polishing pad around a center spindle while the pad freely spins on its own axis. A counterweight on the opposite side of the center spindle dampens vibration for smooth operation. These are known as random orbit dual-action polishers.
This random orbit pattern prevents the creation of swirl marks, paint burns and other forms of paint damage often associated with high-speed rotary buffing machines.
In addition to lack of power, the small polisher machines, sold in retail and automotive discount centers everywhere, have very limited polishing pad and bonnet options. Most of these system rely on an inexpensive fabric bonnet will a pull string for fastening.
Quality professional and pro-consumer car polishers all use removable,
washable and reusable foam polishing and buffing pads with quick change VelcroTM backing.
DETAILER FOR HIRE OR DIY?
Hey, if you can afford to hire a professional detailer to
maintain your cars, by all means, do it! However, before your turn
your car over to a detailer, ask them what kind of polisher they use.
CAUTION: Many detailers use a high-speed rotary buffers.
These machines are very powerful and the polishing pad is driven directly off of
the motor shaft which means the pad spins at a high speed and creates heat.
If the detailer is not very skilled (and careful), their
polisher will leave marks called holograms or buffer swirl and could potentially burn through the paint.
Most good detailers will only use the rotary buffer for very serious defects in the paint, then they will make a final pass with a dual-action machine after
the serious defects have been removed by their high-speed rotary buffer.
WATCH OUT! Inexperienced or shady detailers will cover buffer swirl with a filler polish, glaze, oily wax to hide them from you. When you pick up the car it looks great, then the swirl will magically appear after the next time you wash your car.

- Tape off trim with painter's tape to avoid staining trim and polish build up in cracks and crevices
- Never lift your pad off the paint when the machine is turned on
- Keep the cord over your shoulder and away from your paint
