A refinish basecoat composition includes at least one pigment 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 the hydroxyl-functional acrylic polymer, and a pigment-free component containing the hydroxyl-functional acrylic polymer.

Fast drying basecoat refinish composition

Air-dry refinish primer compositions containing microparticles have been found to exhibit superior air-dry properties as well as being resistant to solvent attack when a primer-surfacer or topcoat is applied after a short (30 minute or less) dry time of the primer composition.
