I cleaned the rotors that I intend to use, soaking them in carb cleaner
for
 a week.  They clean up real nice.  I noticed a patchy light almost looks
 like an adhesive deposit on the side surface located between the side
seals
 and the edges of the rotor.  Does anyone know what this is? Thanks

 It is probably a Teflon coating that reduces the crevasses around the edge
of the rotors
 to reduce unburned HC storage for emissions reasons.

Paul,

I can feel the pitting with my fingernail.  It could be corrosives in the
fuel or oil.  It is on the combusion side.  I will try to get pics.  Also
found a small ding in the rotor face that is far away from the apex slot and
bathtub.

Yep that looks like the Teflon stuff. Not to worry you don't need it.
