Flambeau, one of the industry's oldest tackle-box brands, has been using Zerust technology in its boxes for six years. Zerust is a polymer that emits a harmless vapor that forms a protective coating around metal surfaces, eliminating corrosion and rust.
"It covers all the products inside the box," says David Faulkner, Flambeau's group vice president for retail markets. "You're often talking about plugs that cost $20 these days. That's a big investment, and it only makes sense to take care of them."
Plano, too, offers a specialized Hydro-Flo StowAway utility box, which has holes in the base and lid that allow air to circulate and dry lures. "These pores naturally prevent corrosion," Simpkins says.
