Abstract: The invention provides a method of obtaining improvements in the appearance of articles having both vertically and horizontally orientated surfaces and a coating composition for use in said method. The coating composition of the invention has a film-forming component (a) and a rheology control agent (b) having substantially colorless, substantially inorganic microparticles (i) and a compound (ii) comprising the reaction product of an amine and an isocyanate. A particularly preferred method of the invention requires applying the coating composition of the invention to an article having at least one horizontally orientated surface and at least one vertically orientated surface so as to provide a coated horizontally orientated surface and a coated vertically orientated surface, wherein the coated vertically orientated surface has improved sag resistance, most preferably having a sag resistance of at least 1.2 mils. The coated surfaces are then cured to provide a cured horizontally orientated film having an improved surface appearance, most preferably a surface appearance having a DOI of at least 70.
