With its combined rotary and random orbital movements, the FLEX XC 3401 VRG Positive Drive Orbital Polisher offers virtually the same level of cutting performance as a traditional rotary polisher, but with fewer of the usual risks. For example, thanks to the dominant random orbital movement, frictional heat is generated more slowly, meaning that the chances of overheating or burning the paint are minimised. In addition, the short-throw random orbital movement also ensures that holograms are not formed during the polishing process, which saves time by eliminating the need for unnecessary refining work. When the FLEX XC 3401 VRG Positive Drive Orbital Polisher was originally launched the smallest backing plate available for it had a diameter of 115 mm, which posed a problem for many detailers as it precluded the use of spot pads. However, a solution to this problem now exists in the form of the Lake Country XC 3401 VRG Backing Plate System, which enables 100 mm spot pads to be safely used. The FLEX XC 3401 VRG Positive Drive Orbital Polisher isn't as easy to use as free-spinning random orbital machines, due to the torque steer produced by the rotary movement, but if you have previous rotary experience and are looking for a powerful dual action polisher then it should be high on your list of tools to consider. In experienced hands, it's a supremely capable machine.
