Was speaking to a rep today who was at Nevisports, they're planning on discontinuing the product due to being expensive to produce with only a small customer base for it so if you use it worth stocking up before the price and availability mirrors the silent partner...
Obviously not as good as a factory dry treatment but at the price it's good for improving the handling and giving the sheath more resistance to cuts, abrasions and surface moisture if you're never going to be ice climbing with it vs cost of a factory dry rope.
