Abstract: a method and product relating to a powdered coated resinous article. The surface of the resinous article is sealed to resist the effects of gases released from the article during heating. The sealing layer may contain a lead silicate chromate additive. A conductive exterior surface is then formed on the article and subsequently a powder paint is applied to the article under the influence of an electrostatic field. The coating is then heated sufficiently to merge the particles into a continuous film. The powder coating may be acrylic, polyester or epoxy. The sealing and forming a conductive layer may be done in one operation.
