A patented VCI polymer technology molded directly into specific Flambeau plastics that provides years of hassle-free, long-lasting rust and corrosion protection. How does Zerust work? Zerust-infused plastics emit an odourless, harmless vapour in a contained area to naturally form a protective layer around exposed, clean metal surfaces to prevent oxidation-reduction and stop rust and corrosion.
