1. A coated article prepared by applying a sprayable coating composition to at least a portion of a substrate, wherein the coating composition comprises:

a) a curable waterborne or solventborne film-forming resin; and

b) a catalyst coated on, hydrogen bonded with, contained within or encapsulated by a carrier, said carrier comprising gelatin, polyoxymethylene urea formaldehyde, melamine formaldehyde, or silica;

wherein said applying is conducted to impart shear force to the carrier, which thereby releases the catalyst from the carrier, and upon application of the shear force, at least some of the catalyst is released from the carrier, and wherein the carrier is not formed from the film-forming resin (a).
