Abstract
The present invention is directed to a method of coating a substrate, such as a honeycomb having a plurality of parallel channels defined by the honeycomb walls. The honeycomb has different zones along the length of the channels. The zones are defined by their coating (or lack of coating) and extend for a length of the channel in which there is the same coating and architecture. Soluble components in coating compositions are fixed in their respective zones by forcing a heated gas stream through the channels.
