I use a 3M product that's intended as traction for stairs. It has a sort of rubbery texture, rather than the sandpaper texture of skate tape. I have had the same strip on one of my guns for three or four years, and the edges are still stuck all the way around. I went to the 3M website, and they have a lot of different traction products ("different materials and colors"), and I couldn't identify the exact one I'm using, but I can check the part number when I get home.
