Callington's Silver Zinc Guard Protect is a zinc spray containing metallic zinc, which protects clean steel in the same manner as hot dip galvanising, i.e. by cathodic reaction.

Silver Zinc Guard Protect gives exceptional long-term protection against rust and corrosion and weathers to the same colour as normal galvanising. It is ideal for touch-ups and to hide welded joints on metal structures. It's suitable for all types of ferrous (mild and heavy gauge steel) substrates.
