Abstract: Methods of coating a substrate are provided. In an exemplary embodiment, a coating composition is applied to the substrate with a high transfer efficiency applicator to produce a coating layer, where the high transfer efficiency applicator and the substrate remain spatially separate while the coating composition is applied. A droplet of the coating composition expelled from the high transfer efficiency applicator has a particle size of about 10 microns or greater. The coating composition has a viscosity of from about 1,000 to about 1,000,000 centipoise when the coating composition is subject to a shear rate of about 0.1 reciprocal seconds (s−1). However, the coating composition is non-Newtonian such that a coating composition viscosity decreases when the shear rate is increased to the coating composition. The coating layer is impinged with a gas such that a coating layer surface moves upon impingement with the gas.
