You can get either spray on version or the brush/dip type. I think the spray on stuff would give better results.

One option I hadn't mentioned is a product I've seen hanging on grocery store shelves, a sort of impulse buy type of product. It's a soft rubber mat with a not-quite-checkerboard pattern of holes. The grocery store stuff is inexpensive compared to the industrial version, but I think it's the same stuff. It's marketed as both a shelf liner/drawer liner and a jar opener grip mat. In the industrial world, it's marketed as a tool box drawer liner and also as a sanding mat, used to prevent small parts from scooting away when applying a power sander.
