There is disclosed a metallic and nonmetallic water borne base coat compositions exhibiting excellent appearance. A method for long term stability and the introduction of aluminum flake pigments into a water borne coating is also disclosed. The method is based on storing the aluminum flake in a solvent environment with introduction of the aluminum flake in to the aqueous environment just before appling the base coat coating. A water reducible acrylic resin with nonionic and acid functionality derived from vinyl monomers having nonionic and urethane functionality has been disclosed that allows for direct introduction of aluminum flake in to an aqueous environment. The coating vehicle is based on acrylic latex vehicle which exhibits excellent drying and film properties. The rheology control agent employed allows for a wetter application of the coating to the substrate. The coating compositions disclosed are also in compliance with current and proposed volatile organic compound regulations.
