Topping off with a couple of coats of clear acrylic spray may give a somewhat more metallic look. Then do a brass color outdoor paint, brushed or sprayed as you prefer. Cast iron is porous and you'll probably have rust stain problems if you don't do this. Then apply a phosphoric acid based naval jelly or rust converter. If you can settle for brass colored paint, get any old paint off as best you can by sandblasting if available to you, or by sandpaper and paint stripper if blasting isn't possible. In short, if you want real brass plating, realistically you'll need to be able to remove the claw feet and send them to a plating shop.

Brass colored paint and brass plating (real metal) are not the same thing, so you'll need to decide whether you can settle for the paint or must have real brass plating.Īlthough it is not completely impossible for a hobbyist to do any metal plating at home, brass plating on cast iron would involve sandblasting the cast iron, acid pickling it, nickel plating it (both for shiny appearance and because you can't plate brass directly on cast iron), then brass plating (this is cyanide based), then several well-applied coats of brass lacquer or a 2K automotive clearcoat.

The same process is widely done on firearms, although people then tend to call it 'blueing' rather than 'black oxiding'. Although the corrosion resistance is quite limited, it's an attractive finish that doesn't change the dimensions of the objects like plating or painting does. Industrial gears, sprockets, couplings and chain are black oxided. The black oxide process you are describing is still widely done on things today.
