What is Zerust?


Even thought the box isn’t 100% waterproof, the dividers are made out of Zerust which is a Vapor Corrosion Inhibitor (VCI) that travels through the air to form a protective layer over metal surfaces. This works to keep your baits rust-free in a humid environment and is something you should definitely throw into boxes that do have a watertight seal as well.

Although watertight boxes do a great job of keeping water out, they also do a great job of keeping water in when you open your box in the rain or throw a wet bait back in. You can buy Flambeau’s Zerust Plastabs Rust Inhibitors separately and I highly recommend doing so as I have them in all my hard bait boxes.
