Gary,

Can you help me with some specifics. You said "Orbital machines are for
polishing wax". But if my notes are correct, polishing and waxing are
two different exercises, one preparing the surface and the other
protecting it. Can you clarify?

Also, what is buffing? What is cutting? What's the difference between a
buffer and polisher? 1750rpm and 8 in foam pads on what type or brand
of machine? I see 6, 7, 8, and 10 inch pads; can typical machines
handle multiple pad sizes?

I remember a little less than two years ago going through a state of
careful study mixed with terminal confusion when I was learning about
flight computers, loggers and electric varios. This is déjà vu!
