Zerust Corrosion Control A
nyone who has tackled a complete or partial classic car restoration themselves will know all about rust and corrosion — indeed, a large part of many restoration projects will centre around patching up the long-term damage caused by these factors. However, it’s not just the bodies of our classic cars that can be affected, even items such as fasteners and screws, as well as smaller car parts, can rust away if left unprotected — and as home-based restoration projects can take many months, or indeed many years to reach completion, protecting all the hundreds of parts and fasteners removed from a car during that project can become a major concern.
Fortunately, an effective and simpleto-use method of controlling rust and corrosion is now available in New Zealand — one that doesn’t rely on the timeconsuming application of potentially toxic and messy coatings of grease, oil or paint. Indeed, this system is as simple as sealing the parts that need protecting within a zip-lock bag — how easy is that?
If that all sounds like black magic, then you’ve probably never heard of Vapour Corrosion Inhibitors (VCI). This is the technology employed in Zerust’s innovative range of corrosion-protection products — and the system has long been in use within the military and in the mining industry, proving its worth in inhibiting rust and corrosion on machinery that, for one reason or another, has been mothballed for later use.
Preventing rust and corrosion
The Vapour Corrosion Inhibitors (VCI) utilized by Zerust products — the main ingredient being sodium nitrite — prevent corrosion by releasing a vapour within an enclosed space. The overall effect is rather like the anode/cathode method used in chroming — the vapor corrosioninhibitors forming a protective barrier that effectively interrupts the electrochemical corrosion process.
The vapor corrosion-inhibitor portion of Zerust products is made of proprietary chemical formulations that are invisible, odourless, non toxic, non reactive, non flammable and non allergenic, so are safe to use. The protective layer produced will then remain on the surface of the metal as long as there is no significant, continuous exchange of air.
Zerust’s products range from VCIimpregnated plastic bags and sheathing to small strips and larger capsules, products that can actively prevent corrosion for anywhere between two and five years depending upon the application utilized.
The uses for Zerust are not restricted to protecting parts — pop one of its capsules or special draw liners into your tool box, close it up, and you’ll keep that pesky surface rust away from your valuable tools. Zerust products are even great for keeping corrosion away from inboard engine bays on launches and jet-skis. Vci-impregnated plastic sheath is also available in 200mm and 300m widths and these can be cut to sizes suitable for storing longer items such as propshafts. Indeed, Zerust can even supply VCIimpregnated bags large enough to contain an entire car or motorcycle — seal up the bag and you’ve got the perfect classic-car storage solution.
Even better, the Zerust system is easily affordable, with simple VCI strips and zip-lock bags costing as little as a few dollars — so there’s no excuse not to try Zerust products.
