A curable polymeric material containing ceramic particles preferably a zeolite with one or more antibiotic metals ion-exchanged therein is used and applied to the metal product and cured for an effective time at a specific temperature range to provide the desired metal product. Electrostatic spraying is preferred to coat the article but other application methods can be used.
