We have your typical chain link fence , my husband wants to replace it, but until then I have noticed that ones that are black are not as noticeable and don't look so unsightly. So to test I bought a can of the outdoor wrought iron black and sprayed just a gate and it really does almost disappear in the landscape. So, now instead of buying 60 cans of paint. Need advice. First has anyone done this before, second do they sell that kind of paint by the gallon and I have never used a paint sprayer. Any advice appreciated
