I guess he wouldn't be asking the question if he didn't ? However ....
If the OP isn't interested in originality , then I would suggest primering it in grey primer, then painting the whole thing gloss black . When dry , masking the areas to go silver , sanding them lightly and then painting dark silver or silverish grey . When it's all dry lightly sand the whole thing again , Then clearcoat the whole thing in clear lacquer .
