      For the record I once got back a mirror with a bad coating and a note
      stating that the mirror was not fully polished. I knew the mirror was
      well polished so I sent the mirror to another coater who returned me a
      mirror looking beautiful from center to edge. Coating is an art, I
      conclude, so I treat coater's comments as just that.
