Did some research on Danish DXXI's 10 years ago, and my (Danish) sources agreed the cockpits was painted light grey. I haven't seen the Phalanx-book, but think I've seen the 'aluminum dope'-picture you mention.
This is probably one of the two airframes delivered from Fokker, but I think the 'metal-look' is an optical illusion. I'll try to check my references, when I get home tonight.
