Abstract
The present invention is directed to a method of and apparatus for forming a coating having at least one fade zone over a substrate. The method and apparatus include positioning a coating composition dispenser above a surface of a substrate with the coating composition dispenser oriented to dispense a coating composition spray generally normal to the surface of the substrate. A gas dispenser is also positioned above the surface of the substrate and adjacent the coating composition dispenser with the gas dispenser oriented to dispense a gas stream generally normal to the surface of the substrate. The coating composition spray and the gas stream are spaced from each other so as to develop an interference effect therebetween adjacent the surface of the substrate. Preferably the substrate is maintained at a temperature which pyrolyzes the coating composition. The interference effect directs the coating composition to deposit over the substrate as a coating having a fade zone. In an alternative embodiment of the present invention, a plurality of coating composition dispensers and gas dispensers may be positioned over the substrate to provide one or more coatings on the substrate, each of which possesses at least one fade zone.
