Abstract: A method of manufacturing a bi-layered coating is provided, which includes applying a primer paint on a substrate, wherein the primer paint includes 100 parts by weight of a first polyvinyl fluoride, 20 to 50 parts by weight of an assistance resin, and 150 to 170 parts by weight of a first latent solvent, and wherein the assistance resin is polyester modified epoxy resin, polyester type polyurethane resin, phenoxy resin, or a combination thereof. The primer paint is baked and dried to form a primer coating. A finish paint is then applied onto the primer coating, wherein the finish paint includes 100 parts by weight of a second polyvinyl fluoride and 120 to 150 parts by weight of a second latent solvent. The finish paint is baked and dried to form a finish coating on the primer coating.
