Supah - Indeed, i maybe should have done it less dirty, especially that one.
There is a nice pict of it at a show with Izhak Rabin, showing how shiny and polished it was at the time… here :
Israeli MirageIII N°45
Don't know if it was as shiny during battle though… There was some very dirty ones :
Israeli MirageIII N°60
But that one is a bit extreme
Jester-Ink - Cheers !
Blowhard - Thank you sir !
Ratfugel - Many thanks !

From experience i have found that to make a good metal , better to use a rather dark diffuse color. Most of the light shades comes from reflection . Anyway , that for a shader in 3d, just my 2€ cents…
