Abstract
The method of coating a substrate with plurality of layers of coatings includes moving the substrate along a path through the coating station. A composite layer is formed of first and second coating fluids. The substrate contacts the flowing composite layer to interpose the first coating fluid between the substrate and the second coating fluid. The composite layer is doctored with a gas from a gas knife to remove some portion of the composite layer from the substrate.
