No,hey,you might be right,I'd love the bare aluminium too but it's just a toss up for the nose........possibly in four quadrants ,black,white,black white,like four pieces of an orange,know what I mean? I think some of the very first space rockets were checkered like that too.Zeppelin-like.I can always try it first and if it's no good I can just spray everything again.
An old colleague told me they make fibre-glass impregnated with aluminium so that when you're finished the thing will look like aluminium,maybe that's a possibility.Couple more layers of that stuff on top and it might start looking like something.
