A flexible and stretchable sheet material that is capable of being stretched to conform to a three- dimensional substrate to form a protective and decorative coating thereon is comprised of a thin flexible support having adhered thereto a protective and decorative layer such as a paint layer comprising a colorant incorporated in a film-forming binder. Both the support and the protective and decorative layer are characterized by a very high degree of thickness uniformity and the sheet material exhibits a high level of surface uniformity, an ability to undergo substantial elongation, and a substantially uniform quality and appearance; whereby it can be stretched and bent in the process of bonding it to a substrate and still achieve a defect-free coating of uniformly attractive appearance. A process for the manufacture of the sheet material comprises the steps of: providing a flexible support sheet; providing a fluid protective and decorative film-forming composition; forming a laminar flow of the composition and directing the flow into contact with the surface of the support to form thereon a protective and decorative layer of substantially uniform thickness; and converting the protective and decorative layer to a dry and tack-free state. In one preferred embodiment, the protective and decorative layer comprises a film-forming binder, a colorant and generally flat light-reflecting particles which are effectively oriented by the laminar flow process to provide a layer characterized by a high degree of geometric metamerism. Vacuum-forming and thermoforming techniques can be effectively employed to bring about the application of the sheet material to structural substrates, such as exterior automotive panels, to which it can be glued or otherwise securely bonded in a smooth and wrinkle-free stage.
