[painting a chain-link fence]

If there's sufficient room under the fence, I wonder if you could hook up a very low pressure recirculating pump to more-or-less pour paint onto the fence and catch (and recirculate) the runoff. This is the factory method they use for painting prefabricated/painted wooden fence sections.
