This multipurpose lubricant is more than just a zipper wax, it also protects nylon, plastic, and metal zippers against salt, chlorine, rust, and corrosion. It works great on toothed dry suit and older bow bag zippers to keep them running smoothly. We recommend TiZip's silicone grease for the Cargo Fly Zipper but this is an acceptable backup if your tube runs out.

The 4.5g size is about the size of a large tube of lip balm and has plenty of lubricant for a season of heavy use.

Use instructions: 
Clean out as much grit/sand/dirt as possible when open, then zip closed and apply directly to zipper chain. Slide zipper pull back and forth to evenly disperse. Use clean cloth to remove any excess.
