Bernie:  perhaps you don't have the same issue as those of us on the east coast.  Out here, the brake rotors rust, starting at the outer and inner edges of the rotors (also filling the vented areas; that's another issue entirely).  The rust actually seems to creep in, get polished by the pads, then provide a poor braking surface (thus just the center 1" of the pads does the braking).  It _looks_ like rotor surface, almost.

On a car that's been sitting, a metal scraper can be used to remove this polished layer of rust off the outer/inner edge of each side of the rotor; might get you some more life out of the rotors.  Probably going to feel some brake pulsations, though.

Cad plating new rotors might prevent this.

  If the pads only make contact with the rotors in a 1" center stripe of the
  2.5"+/- width of the pad, most likely the LOL didn't know what the brake
  pedel was for.  Rust will not accumulate in the critical areas when they are
  used as intended.  I'm not a heavy brake user, in fact, I will use engine
  braking as much as possible in everyday driving of the Sierras.  But they
  will stop these heavy cars when called upon.  What is this "its only a
  matter of time before things start to pulse and shimmy"?  No justification ,
  except brainwash!  It may take you a few hours and no $ to insure that your
  UFOs are in good shape, but then these upgrade people need your financial
  support.  A thin wallet feels SO good!  Your decision.
