No matter what brand or type of bowling ball you choose, it loses performance. One of the reasons for this is "lane shine." Over time, all bowling balls end up around 4700 grit. When this happens, it changes the performance of the bowling ball. Thanks to TruCut Sanding Pads, you can maintain the surface of your bowling ball to reduce lane shine. Creating the Difference partnered with a leader in the abrasives industry to develop sanding pads MADE FOR BOWLING. TruCut Sanding Pads cut a bowling ball at the grit listed on the pad. Available in both 5" and 6" diameter and in the following grits: 500 1000 1500 2000 3000 P5000D (4000 grit by hand or 5000 grit with a ball spinner) TruCut are available by single pads and in packs.
