Hallo everybody and thanks for the kind words...
@Ondra: for the fuselage I used Tamiya TS-83 Metallic Silver spray in rattle cans.
But the forward part and the cowling were brush-painted with a common glossy black before.
See here a more clear picture of the difference:

The same spray colour made a different result on the wings, stains and different shaded areas... so in the end I rubbed the first coat of paint off the wings and used a different can: TS-17 Glossy Aluminum.
I hope this helps!
Ciao
