It says in the article that BMF can be painted after you coat it with Future. Has anyone tried this:
From the article:
Apply several coats of Future acrylic floor polish with a flat, carefully cleaned brush or with an airbrush. Future seals the foil, protects it from oxidation, and forms a primer coat that is needed under any additional painting or weathering. (Enamels, artist’s oils, lacquers, or acrylic paints don’t adhere well to bare foil.) Future also adds to the luster of the metal, and forms a perfect surface for the application
of decals.
