Blue Oxide is a treatment for metals on carbon and stainless steel. This Blue Oxide is a spray on ceramic durable that can only be finalized with a matte finish. Includes removal of dents and scratches, stripping of previous finishes, if needed, and color fills up to four colors. We suggest contrasting colors which stand out against the deep blue and make your putter a conversation piece. This putter requires less maintenance than an oil can but will still need to be kept dry and oiled after use.
