Disclosed herein is a method of preparing a game ball mold cavity for application of a coating system. A dual region coating system for a game ball mold and a coating application method also are disclosed. The mold preparation method provides for a longer use of a game ball mold than results when conventional mold preparation techniques are used. The dual region coating system comprises a fluorocarbon polymer in the hemispherical opening of the mold cavity, and a metal, such as nickel, impregnated with a fluorocarbon polymer on the land area. The dual region coating system of the invention is particularly useful for making golf ball cores containing zinc-diacrylate and/or zinc dimethacrylate, as these materials tend to adhere to the walls of a mold cavity.
