The one thing to watch out for with copper paint is that as soon as it has been painted and fully dried, the copper particles will slowly start to oxidise. On a graph of conductivity over time for copper paint, you would see a bell curve. The conductivity increases as the paint dries, until it reaches its peak when it has fully dried, then drops down as the copper starts to oxidise. When the copper has oxidised the part will no longer be conductive and will not electroform. The optimum time to use a copper painted part is as soon as it is fully dry. One final thing to note about copper paint is that, in some paints, the copper is in flake form. Meaning that you must apply the paint quite thick (to make it look wet) so that the flakes can settle and become smooth and flat.
