This oil can finish is available only for CARBON STEEL. Each putter is carefully refinished by hand to remove any dents and scratches. It’s stripped of previous finishes and paints in preparation for the one of a kind Chromatic Rainbow finish. The purple coloring is achieved by heat tempering the steel. The refinish includes paint fills of your choice, up to four colors. The final finish is high sheen and 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.
