Use Zipper Wax to protect watertight zippers from rust, corrosion and salt in all temperatures. Previously known as Max Wax, this paraffin-based stick formula lubricates plastic and metal zippers on wetsuits, drysuits and more. Just glide it along zippers to extend its life and prevent costly repairs to gear.  A stiff, stuck zipper is useless. Keep them sliding like they should with Zipper Wax.
