A sticky zipper is usually a dirty or dry zipper, and this is the fix. Rub the wax on the teeth and the pull runs smoothly again. It protects nylon, metal and plastic zippers from salt, chlorine and corrosion, and the wax does not flake off. It works on tents, packs, jackets, wetsuits and drysuit zippers, and is worth a spot in the boat bag.
