    Abstract: The object of the present disclosure is to provide an automobile part capable of improving fuel consumption by weight reduction of the part because the impact resistance that can be sufficiently used even in cold regions can be given to a part made of a thinner plastic.
    An automobile part obtained by forming a coating film layer on a plastic material comprising a polypropylene resin composition modified with an elastomer component having a thickness of 1.5 to 2.5 mm,



    wherein said coating film layer is a multilayer coating film obtained by coating and baking the following coating compositions in this order;
    (a) a primer coating composition having a single film tensile elongation of 5 to 35% at −20° C.,
    (b) a base coating composition containing a coloring agent and,
    (c) a clear coating composition containing at least a linear acrylic polyol (c-1) with a hydroxyl value of 80 to 220 mgKOH/g, a crosslinked acrylic resin (c-2) containing 2 to 30 parts by weight of polyfunctional monomer (c-2-1) with 2 to 4 radically polymerizable unsaturated groups per a molecule and 98 to 70 parts by weight of monofunctional monomer (c-2-2) with one polymerizable unsaturated group as a constituent unit, and having a glass transition point of 70 to 120° C., and a curing agent (c-3), and
    wherein the coating film layer has a Dupont impact strength of 4.9 J or more at −30° C.
