the base metal is the original part with no coating or finish of any kind. parts that are blued, are polished on buffing wheels until they look almost like chome, polished. matte finished parts usually simply bead blasted then blued. blued or matte finish uses the same chemicals to acheive the finished look. the preparation is just different. blueing is just controled oxidizing or rusting.
don't understand your question about the duracoating.
