Whether you are putting your bike in storage or just want to keep it spotless, this effective cover offers 5 years of rust protection. ZerustŪ is a Vapour Corrosion Inhibitor (VCI) that emits an invisible vapour, settling on metal to prevent rust and corrosion. The VCI formula is invisible, odourless and non-toxic and dissipates off the bike when you remove the cover.
