I recently bought a big spray bottle full of Rain-X to use on my hard mouse pad and mouse feet. It works so great I just thought I'd share and pass along the info. A long time ago, I followed the suggestions of people who swore by Pledge on mouse mats. It worked well, but it was messy and didn't last long. As to Rain-X, so far so good. I have a Logitech G5 and a C4 N-Gen mousemat and can't complain! If you need the slickest surface for gaming or you just like a smooth-as-ice feel, I recommend this strongly.
