A refinish basecoat composition includes an alkyd resin, at least one pigment dispersed by resin comprising the alkyd resin, and an hydroxyl-functional acrylic polymer. The acrylic polymer has a number average molecular weight of at least about 6000 and is polymerized using at least about 45% by weight cycloaliphatic monomer, based on total monomer weight polymerized. A mixer system that can be used to prepare the refinish basecoat has a plurality of color components, each independently including at least one pigment dispersed by resin including an alkyd resin, and a pigment-free component containing the hydroxyl-functional acrylic polymer.
