I've used it and it's a great product if your looking at those inhibitor chips for baits/hooks but I've found that just leaving my box open or keeping my plano's cracked open works just as well. I'll usually leave all baits used that day out on the casting deck in tubes to dry. I've also heard those silica gel stuff that comes in new shoe boxes works well too. They will soak up any moisture.

Some tackle boxes, like my big Flambeau, have similar anti-rust protection built in. Flambeau uses Zerust. They say it's good for at least 5 years, so it has a limited lifetime. It's hard to find any detailed info about what it is or how it works, but presumably it does work.

Thay also sell it as an add-in:
