Thanks Guys
Weathering? that was easy
Description below - based on Gunner post (Thanks Gunner for help

)
The panel lines on the wings and fuselage were done drawing the lines with a Top Flite panel line pen (bottom and upside). Then upside (all where blue) I masked ech side if the line with scotch blue tape leave a gap no larger than 1mm. Then using small brush paint disorderly with silver humbrol.
The lines on the front on fuselage: after topflite pen was made (without scotch tape) very disorderly (on the "srews" also) with small silver brush .
The oil streek effect I made: first applying scotch blue tape to the upwind edge of the panel. Put some tiny spots of black pain (flat humbrol) in the middle of the masking tap and with paper towel smeer them off the edge of the tape.
That's all
