The term 4% refers to the specific thickness reduction applied during the skin pass process. A 4% reduction is typically sufficient to eliminate any surface imperfections while retaining the structural integrity of the material. This technique is especially valuable for high-quality applications where aesthetic appearance and surface integrity are critical.
