Abstract
A clearcoat composition and method reduce the ability of rain to bead on a film of the clearcoat. The clearcoat includes a resin, a cross-linking agent reactive with the resin, and a water-soluble surfactant. Upon exposure of the film to the rain, the surfactant reduces the ability of the rain to bead on the film and certain properties, such as resistance to etch from acid rain, are improved.
