As many times (I guess) the search of new materials works great, and this is wath happened to me.
The result is the next pics, I simply thought, if the pastel chalk mixed with water works fine, maybe an water base marker could do...and yes, it works.
The first Terri advice, the model was painted with oil base paint, so the weatering material is water base.
The scarry was present when I started to paint the plane with the dark brown marker...aaahhhh!!!!!!! buy with some cotton cleaned the exes, and some water drop, cleaned more. Until the wanted finish apear...I found the happy feel

The line betwen the rim and weel, the line after the cowling, the aileron lines and ribs.
Thans again.
Cheers.
