DLC is a Diamond Like Coating is a coating process similar to a PVD used on specialty steel, carbon steel, aluminum, titanium, nickel, brass, and more. The DVD process occurs in a vacuum at working pressure and involves bombardment of the putter to be coated with energetic positively charged ions during the coating process to promote high density. This DVD finish on your putter is about performance. The life span of this finish is exceptional with a liquid smooth feel off the face to ensure you are focused on your game, rather than your putters maintenance. The DVD refinish includes removal of dents and scratches, stripping of previous finishes, if needed, and color fills up to four colors. Final sheen comes in matte, satin, or polished.
