A curing composition, for use in curing of an acrylic polyol-containing coating composition, contains from about 20 to about 70 percent of an aliphatic polyisocyanate, from about 20 to about 70 percent of an aliphatic polyisocyanate prepolymer, from about 0.01 to about 5.0 percent of an ultraviolet light stabilizer, and from about 0.25 to about 5.0 percent, based on the weight of the solids of the curing composition of a metal catalyst, and from about 20 to about 70 percent of an organic diluent, based on the total weight of resin and diluent of the curing composition. The curing composition provides a fast cure for the coating composition while having a sufficient gel time to allow practical application thereof the a basecoat.
