The Rusty Bucket finish can be applied to Carbon Steel putters only. This finish is accomplished through a 6 step chemical conversion coating process. Each step allows the putter to continue to patina into a rusty brown color with orange accents. This finish is perfect for the golfer who likes the look of a natural patina worn look that carbon putters develop over time but instead of waiting you can get the finish instantly. All dings, dents and scratches are removed and this finish can be performed in a matte finish.
