1. Method for coating a substrate having a plurality of channels with a coating media comprising:

  • a) partially immersing the substrate into a vessel containing a bath of the coating media, said vessel containing an amount of coating media in excess of the amount sufficient to coat the substrate to a desired level;

    b) applying a vacuum to the partially immersed substrate at an intensity and a time sufficient to draw the coating media upwardly from the bath into each of the channels for a distance which is less than the length of the channels to form a uniform coating profile therein; and

    c) removing the substrate from the bath.
