CitabriaI like the 109 and 190f8 best. you wont be able to tell its metal though unless you fake some reflection on it using a bit of blue and such where its natural metal
The F8 originally had the blue thing going. Back before the new 51s and 47s came out, I wanted to learn how to do metal so I'd be ready for them. About that time, TexMurphy posted up some great how-tos on metal, including the blue trick, so I did a completely bare-metal F8. I'd just finished doing some A8s so basically had the template already, and had stumbled across a real nekkid F8 in a book, so it was the perfect quick project for me. Came out great and has been in the game for some time now.
So when I did this 1/2 nekkid F8, I just painted over parts of my previous F8, leaving the metal as it was, Tex-style, including the light blue layer and the material.txt file with the B values an RCH higher than the R and G. I quickly discovered, however that this wasn't going to work. When I turned down the diffuse and specular values in the material.txt file so that the painted upper parts wouldn't glint like they were bare metal, it also took a lot of the glint out of the metal parts. This in turn made the blue show up way too much, so the plane looked like it was painted with RLM 65 or 76. So there was nothing for it but to really turn down the opacity of the blue layer, plus get rid of the B bias in the material.txt file.
The result is that the metal parts now look like light gray paint from most angles. However, when the light catches them just right, they still glint brightly like the bare metal they're supposed to be. At the same time, the painted parts really don't glint much at all. So I think I arrived at the best compromise, given that the material.txt file applies to the whole plane, not just the metal parts.
Here's another view of the F8 showing the metal glinting, while the painted parts ain't.:
