Raw finish club heads are meant to rust and create a patina over time. They will arrive with a dull satin appearance but do not actually have a finish applied to them. These heads will begin to rust and build character as they are introduced to moisture and the elements.
Black finish club heads offer a clean, distinct look while also limiting glare and other distractions for the player. The Black QPQ finish has been developed and tested extensively. It provides a significant durability upgrade from the standard Tour PVD finish while providing more of a matte black look.
