This oil can finish is available for CARBON STEEL only! Each putter is carefully refinished by hand to remove any dents and scratches. The color is achieved by heat tempering the steel which creates color hues such as grey, wine, purple, and blue. The refinish includes paint fills of your choice, up to four colors. The final finish requires maintenance similar to raw metal. It needs to be kept dry and well oiled to prevent rusting/patina. This item is a great addition for the golf collector and is not recommended for frequent play.
