When you buy the Gravity Shift as I recently have, there should be a little piece of paper included in the box. This paper includes stuff like coverstock, weight block, flare potential and that stuff, but below should also be a little diddy on how to bring the ball back to factory finish using i think something like 230, 300, 500, and 600 wet/dry grit sandpaper then using #2 step storm polish on it. So if you still have the box and the drilling guide with all the papers it should be tucked right inside.
