Hi 210 cav. To be honoust, it was my first attempt, but here we go: First the normal base coat of olive drab ( Humbrol 155 ), after that I simply used NOT well stirred matt white ( Humbrol matt 34 ). To lighten-up the streaks, I don't know if thats proper English, I re-used the olive drab. Then I washed with a very dilluted wash of white spirit and some Raw Umber oil. When dried, some dry-brushing with the lightest shades of gray I could find...sorry I don't have the numbers.
That was it in a nutshell,
Hope I was of any help, John.
