Shurhold Snap Stick Snap & Zipper Lubricant 
Snaps and zippers on awnings, straps, and other items suffer the corroding effects of rain, dirt, and grime. The result is often a mechanism that either sticks or rips the surrounding canvas or plastic. A simple alternative to fighting with snaps or zippers is a quick dap of water-resistant Snap-Stick lubricant, which comes in a handy tube similar to Chapstick.
