Candy color metallic paint finishes can be formed or repaired by applying to a substrate a colored liquid base coating composition containing a colored metal oxide-coated nontransparent silver dollar aluminum flake pigment and optional additional colored pigments or dyes dispersed in a first hardenable binder to form a reflective colored base layer that hides the primed substrate and has a sparkling metallic appearance. A colored liquid intermediate coating composition containing a colored pigment or dye dispersed in a second hardenable binder is applied to the base layer to form a colored intermediate layer that increases the color saturation of incident light reflected from the base layer. The intermediate layer can be overcoated with a liquid clearcoat composition. The completed finish can replicate an original equipment manufacturer multilayer candy color metallic finish, while providing ease of application, low sensitivity to layer thickness variation, and low mottle.
