The resin is selected from the group consisting of alkyds, acrylics, polyesters, hydrocarbon resins, rosin-based resins, polyamides, urethanes, and epoxies. The solvent comprises aliphatic and aromatic hydrocarbons. Ranges in weight-percent for each of the components is set forth, as well as a specific formulation.
