This type of polishers can only be used by polishing experts or professionals. The rotary polishers , in fact, can correct imperfections much faster than the random orbital polishers and rotary eccentric but the their use requires practice and competence as they can cause damage to the paint more frequently. Due to the frequent damage created by the pads that turn at different speeds (inside more slowly and with greater vigor) it is always recommended to finish the work performed with this polisher with a random orbital.
