Purple Oxide is a treatment for metals on carbon and stainless steel. Purple Oxide is a spray on ceramic finish 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 vibrant, fun colors such as yellow to stand out against the deep purple and make this your next favorite putter. This putter requires less maintenance than an oil can but will still need to be kept dry and oiled after use.
