Messerschmitt Bf 109G-4 W.Nr. 14851

 

 

 

 

NOT the same aircraft!
 

 

 

 

 

This is how I am trying to do pre shading and post shading all in one go...
I do some fine line with the final color color (Gunze RLM74 in this case) on a white primer coat (Gunze 1500) following panel, rivets and other lines on the surface, leaving some white showing through- 

Then I fill in with some mist of the same color, highly diluted, light repeated passes. 

Final result, not very obvious in the photo but it is visible, even if subtle.
Oils filtering will do the rest
