I just used some sand paper and rubbed on the side of the Grand just using my finger. I didnt care how it looked. My Grand is a beater. Some have used dremels and made a small spot where the ground of the Kick touches the side or the back. My area of contact is much larger than needed. If you place the Kick in the Grand before you sand you see exactly where it needs sanding. I put a little film of Noalox on that area and also on the top and bottom of the Kick.
