Abstract
A method of using a powder product consisting essentially of thermoplastic or thermosetting polymer based plastic particles and mutually separated, metal flake particles which lie with their faces attached to the surfaces of the plastic particles, said method including applying said powder product to a surface and then melting the plastic particles to form a continuous film on the surface, this being followed by subsequent solidification of the film to obtain a coating of the surface. In an alternate form of the invention, the metal flake particles cover the plastic particles, the quantity of metal flake particles being such that coalescence is inhibited to give a rough, frosted metallic appearance to the surface.
