Rumor has it that the white distemper used by both the Luftwaffe and the Russians tended to wear off during the course of the winter. When I did my Sturmovik on skis, I decided to try to get the appearance of really seriously weathered-off white.
I first painted the regular 3-color camo in its entirety. Then I lightly sprayed white in varying degrees, letting the camo show thru here and there. Then I started picking out panel lines with dry brushing of the camo colors. Lastly, I went over all the panel lines with chalk pastels in the camo colors.
It came out a bit harsher than I'd planned, but it was a fun experiment:
