The same safety feature which reduces the possibility of damage from a dual action polisher also prevents it from removing very deep scratches. While a dual action polisher will improve the appearance of scratches and remove most swirls, it does not produce enough kinetic energy (heat) to cut deep into the paint.
If you need deeper scratch removal, this will require a forced rotation or rotary polisher.
Keep in mind, these polishes in inexperienced hands can quickly ‘burn’ the paint. Especially on panel edges. The pad spins at high speeds and it's up to the operator to keep the polisher moving at all times. If the polisher lingers for too long on one spot, it can burn through the paint.
Forced Rotation Dual action machine has both a centrifugal and a centripetal motion (RPM) and a direct drive orbital (OPM) motion with forced rotation, which means that the back plate rotates by a gear mechanism in a forced circular motion, as the back plate rotates it also oscillates in a random pattern. One action is the circular rotation and the second action is the random movement of the backing plate while it is rotating.
This type of motion is 50% faster at accomplishing the desired results than a dual action machine.
What makes this type of movement ‘safe’ is the comparatively lower torque electric motor on these units, so that it's virtually impossible to apply too much-concentrated pressure in one place at one time
. Chances are good that when too much pressure is applied, the oscillating action will come to a stop thereby protecting the finish.
similar power normally associated with direct drive rotary buffers but the in-built safety of dual action polishers
. It is almost impossible to ‘burn’ or install paint swirls as long as you use approved pads and products. A forced rotation polisher exhibits the best of both worlds.
A forced rotation polisher (Flex 3401) polisher is a German engineered forced rotation action. Featuring VR microprocessor control with tacho generator constant speed control, soft start, continuous speed control trigger, restart protection after power failure, overload protection, temperature monitoring and speed selection. Ideal for professional and enthusiast details alike
Forced rotation is ideal for:
* Detailers who have used dual action polishers and are ready for the next step.
* Detailers who are new to machine polishing but able to learn quickly.
* Detailers looking for a safe, but more powerful polisher as compared to a traditional orbital buffer.
* Anyone wanting to start a part-time or full-time detailing business.
* Anyone with a detailing business that wants to add a multi-purpose tool to their detailing arsenal.
* Detailers that work in body shops looking for a tool to ensure a swirl-free finish.
* Boat Detailers/owners looking for a better way to maintain their boat.
* Airplane detailers/owners looking for a safer, faster way to maintain their aeroplanes' finishes.
* Vehicle with dense (hard) paint forced rotation will provide a far better finish.I've used them on a few German vehicles and along with Menzerna diminishing abrasives, it is more than adequate.
* The smooth running produces a flawless and hologram-free finish
* Forced rotation offers far more correction ability than a dual action polisher
