Using an epoxy other than a latex one could be more of a hassle than a help in certain situations. First most epoxies in general are designed to be very hard cured finishes, on a flexible surface this can mean the epoxies will delaminate or "pop" off the surface with any movement. Any oil, or alkyd finishes on a galvanised surface with result in eventual saponification which is the result of a reaction between the zinc and the alkali. If you use expoxies especially solvent based epoxies make sure you allow sufficient "gassing" time for the solvents to gas out of the finishes film. I once saw the result of a bird bath painted with an epoxy, dead birds all around the house. If it is a one part epoxy it's just fancy paint. I would suggest a DTM or Direct to Metal finishes after the rust has been treated with the fore mentioned products and sanded to a smooth surface. DTM's are normally modified acrylic paints that are expensive but pretty much harmless. As for those darn monkeys......I had a very negative encounter with a service monkey at a newstand in Brunswick, ME. I was admiring this cute little monkey that was being trained to help handicapable people when it suddenly jump on me and sank it's canines into my right shoulder. Boy did it hurt. I swore the rest of my days to irradicating every primate from the face of the planet, well okay that's not really true but I see monkeys for what they truly are, wild animals.
