In substrates, such as wood substrates, having sharp edges, corners and other surface discontinuities, in a front appearance surface, non-functional machining, such as formation of grooves, is performed on the rear non-appearance surface adjacent the surface discontinuities. Coating powder is applied, e.g., electrostatically, to the appearance surface of the substrate and the coating powder fused or fused and cured to form a continuous coating on the appearance surface of the substrate. The rear surface machining reduces cracking of the coating at the front surface discontinuities. In some cases, non-functional machining is distributed over the entire non-appearance surface of the work-piece to promote out-gassing of volatiles to the non-appearance surface, thereby eliminating out-gassing-caused defects in the coating formed on the appearance surface.
