Yes it was spray paint. I used a base of gray primer. Once dry I misted it lightly with water then used duplicolor chrome and misted the tank with the water still on the tank. Once paint was dry I wiped off the water and added another mist of the chrome paint. What you see is the result. It took several attempts but I think it is close to what I have at work as far as galvanized metal for reference. Remember that the look of galvanized will be different depending the process. Here is what the tank looked like before.
