i asked this in another thread, but i thought i`d give it a bump:
okay, i have a really really newbie question (bear with me please )i bought a pc and started to use it on my car with 3m perfect it. i realized after buffing for a while that the perfectit wasn`t breaking down into a finer and finer solution as i`d expected it to.
i inspected the pc and realized that it doesn`t really have a motor to rotate the head (i know it`s orbital and not rotary). but i figured it did both. while it`s running i can use my hand to stop the rotation of the pad altogether, not the orbit however. is that the way it`s supposed to be? my only previous experience (long ago) was with a pneumatic rotary buffer which, obviously, has tons of cutting power. is my pc broken or was i just mistaken in thinking that it had a motorized rotation in addition to the orbit? or does it work simply by vibrating very quickly on the surface?
