Ronin,
Care must be taken in preparing the surface for the bluing operation (I am referring to buffing). If care is not taken, the results will reflect the lack of experience of the person executing the operation. It would be best to consult Thor for advice about the best procedures to give excellent results and reference materials.

If you are thinking of a kitchen sink operation, I would try to dissuade you from attempting it. Again consult Thor.
