Abstract:
An aqueous liquid solution containing soluble salts of coloring metals—particularly manganese and ferric iron along with a sugar source and fulvic and/or humic acid can be readily applied to galvanized metal surfaces impart a natural color tone to such surfaces. In this manner the visibility manmade structures like fences and guardrails is quickly and easily reduced and readily blended into the natural background. The liquid solution can be readily sprayed on galvanized surfaces. When the ambient temperature is warm natural color will develop two-three weeks.
