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 DLC 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. The DLC 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. This finish requires less maintenance than our black oxides, but should still be kept dry and wiped down to avoid spotting from chemicals on the greens.
