A coating composition contains an active hydrogen group-containing polymer (e.g., polyol and/or polyester) and a polyisocyanate curing agent. The polyisocyanate curing agent contains (i) at least 5 weight percent triaminononane triisocyanate, and (ii) at least 5 weight percent of a polyisocyanate different from (i) wherein the percentages are based on the total resin solids content of the coating composition. The composition exhibits a combination of good adhesion and rapid dry time that makes the composition particularly useful as an automotive refinish coating.
