I got some from here.
RJ has this on his smed, it really helps. We use it around the traction, so you don't slip off when on edges of traction. If you just cruise, hula deck by itself is just fine, but I think if you ride more aggressively, you want hula deck with traction on top of it. Dennis hooked us up with this stuff, good stuff.
