thank you Pete
if it's the part that I think I've painted it with tamiya nato black
thank Toby for your comments
another view of the engine

so after my problem with the wing I've decide to repaint them
masking décals and one spray of the misc of silver and smoke
the wings became less darker


for me the result is acceptable
I put the décals on the lower wing
I use wingnut wings décals and it was not very easy to put
I use my méthod a combination of tamiya thinner X20A and hair dryer


I found this decals "too fresh" but I don't know the méthod to "old" them it's the first time for me
can anyone give me a method (ink, oil paint etc...)
thank
