Hello, same colors for upper surface of the lower wing
OK, I surely exagerated a little bit oil marks...
i will see how it lools like at the end; it's only a PE part easy to clean if I want to paint it again...
I started a weathered plane so...
this pic show there was oil under the engines anyway...
here how to will loock like; I think it won't be too much at the end...
