A method of electrocoating the surface of an article such as the internal surface of a can body using as electrode a mandrel having an external surface of substantially the same shape as the surface to be coated. The can body is positively located in a cell containing the mandrel by way of a seal in the cell wall and a limiting surface such that the internal surface to be electrocoated is substantially equidistantly spaced from the mandrel. Electrocoating fluid is flowed by way of a central bore in the mandrel between the mandrel and the internal surface and one or more electrocoating pulses are applied between the mandrel and the can body to electrocoat the internal surface thereof.
