Sky Blue Oxide is a treatment for metals on carbon and stainless steel. This Sky Blue Oxide is a spray on ceramic finish that can only be done with a matte finish. Includes removal of dents and scratches, stripping of previous finishes, if needed, and color fills up to four colors. We love the look of a funky, fun putter with yellow or orange paint fills which accent the uniqueness of the Sky Blue Oxide finish. This putter requires less maintenance than an oil can but will still need to be kept dry and oiled after use.
