I agree with Stang here. While it wouldn't have a "POW" type glare of some BMF skins, I think the specularity needs to come up a good deal. Further, the overall finish has a bit of a blue hue that I think needs to go away.
There's a P-51 based in Carson City, and the owner painted the entire plane in an aluminum metalic paint job (I'm assuming for corrosion prevention purposes just like this one was) and until you get up close, it merely looks like a very consistent BMF. Not a polished aluminum finish, but certainly not quite as flat as what you're showing in the screen shot.
My two cents,
