Paddled two weeks ago in salt water and apparently did not rinse off my deck bag properly. I now have a zipper stuck in the closed position with little white deposits on the head. It does not want to move, and of course, I don't want to break it.
My wife says WD-40, its good for everything! but her level of expertise is like mine, somewhere between incompetent and dangerous.
PS Please don't chastise me, I am sure some of you ocean padddlers have done the same thing!
