Described is an aqueous chip resistant coating composition exhibiting a viscosity of at least 5,000 centipoise, preferably containing binders with a high molecular weight, preferably at least 20,000. Although these coatings may be applied to a variety of substrates, for coating electrocoated substrates the following eight binders are particularly preferred: ethylene vinyl acetate copolymer, carboxylated ethylene vinyl acetate, epoxy functional acrylic resin, carboxylated styrene-butadiene resin, carboxylated acrylic, hydroxy functional acrylic, self-crosslinking acrylic; and carboxylated PVC acrylic. Generally, it is preferred to apply the chip resistant coating via an airless spray and the heat curing the coating.
