the pc is an orbital buffer/polisher. it should handle most detailing jobs on its own. a rotary buffer is used for tougher scuffs/surface defects that orbital simply cant get out but its also more prone to damage the paint too if u dont know how to do it. most detailers say forget the rotary and get lots of practice with an orbital like the portercable before trying to implement a rotary into your detailing tools. anyone correct me if i misstated something
