CRC 6-56 protects from salt really well...when I was running the salt, sprayed all my tools with it..as well as all cable linkage points, etc.I'm a big fan of the Wave. I've owned many over the years. My only issue with Leatherman is they don't hold up well in a saltwater environment and I've yet to figure out a way to prevent them from corroding and becoming super tough to use. As such I tend to just go through one a year. Expensive, but so friggen handy to have on a boat.
