A hollow plastic article of a one-piece construction formed from a molten plastic resin by a gas-assisted injection molding system wherein the article is designed in such a way that any gas channel read through is hidden at a "Class A" convex surface thereof. The article includes a hollow body section and a solid wall section which extends downwardly and rearwardly from a front wall of the hollow body section. The solid wall section and the front wall immediately adjacent to the solid wall section define a convex, sink-free, exterior surface of the article to hide any gas channel read through.

[ What is claimed is:] [1.]1. A hollow vehicular plastic article of a one-piece construction being formed from a molten plastic resin by a gas-assisted injection molding system including a mold having an article-defining cavity and an injection aperture wherein molten plastic resin is injected through the injection aperture and wherein pressurized fluid is communicated to the molten plastic resin in the article-defining cavity to at least partially distribute the molten plastic resin, the article comprising:a gas-assisted, injection-molded hollow plastic body section including a front wall, a rear wall, and interconnecting top and bottom walls formed by the pressurized fluid to define a closed channel for the gas assist which extends at least partially through the hollow body section;a solid plastic wall section connected to the front wall and which extends downwardly from the front wall toward the rear wall immediately below the bottom wall; anda class A, convex, sink-free, exterior surface extending along the exterior surface of the front wall and the solid plastic wall section.
