As Grayson mentioned, the resurface instructions are on the L\LM webpage. Go to
www.lanemastersbowling.com. Once you get to their home page, on the left hand side, click on the "technical" button. After you click on that, a page with all the balls will come up. Hover over the ball (don't click) that you want the info on. Once you hover on the ball that you want to know about, all the tech specs will come up, including how to resurface (near the bottom). There may another way to get the same info, but that is the way I found it.
