I explain what I got (in a plastic part of the plane) on the aluminum did a layer of black very highly diluted was almost solvent with a little paint on this layer gave matt varnish and finally some polished aluminum.
pity that the photos do not appreciate the color worn
the last pics before moving on to the subject of the finished plane, the decals already placed, the lack of gates placed bombs and guns will Colocare machine guns from the gondolas of the wings.
