I know of electrically conductive paints, but I'm looking for a a substance/product that can be painted to a non-solderable surface, let dry, and then soldered to. Anybody know of such a product? This is not an electrical application, so conductivity or other factors not important, I just need the solder to stick. Also, this would be a substitute for adhesive backed copper tape/sheet material, so this need not be suggested as an alternative. Thanks in advance for any help.
