Abstract: The present invention provides coatings comprising a substrate coated with one or more than one colored primer layer comprising one or more than one binder chosen from a resinous or (co)polymeric primer or adhesion promoter, and one or more than one basecoat color layer thereon, wherein the color of each of the basecoat layer and the colored primer layer are the same. Preferred coatings comprise single colored primer and basecoat color layers to make color coatings having a reduced film build, i.e. two layers. Binders for making primer coating layers may comprise weatherable primer resins or (co)polymers, or may comprise adhesion promoters chosen from modified isotactic polypropylene (MPP), MPP copolymers, chlorinated polyolefin (CPO), and their mixtures with alkyds or acrylics. In addition, the present invention provides methods for making coatings on substrates such as thermoplastic polyolefin (TPO), polyolefin containing or metal substrates.
