With the world of non fluorinated waxing, how the product is applied and finished can make a tremendous amount of difference in speed and durability. BNS has found that this Rode Roto brush in merino wool is perfect for the last polish on the ski base and adds to the initial speed and durability of the wax. The wool microfilaments penetrate deeply into the incisions of the structure, leaving the ski with a lively and shiny appearance. Like we always say: A shiny ski is a fast ski!
