Yes, it has, and it's quite effective.
It looks great overall, but perhaps a little too 'stark' in places. If it's possible to reduce the effect slightly on some of the panel lines and rivets, making it a little more subtle in some areas, I think it would improve the overall effect - maybe a grey wash or tint, rather than the harsher black ?
I like the weathered and faded look of the bare metal, and this, together with the overall worn and grubby look, is what I eventually want to achieve on my Fennec (when I get around to finishing it, that is !!), so I'd be interested to see what can be done.
