I painted my M163 in a winter MERDC scheme and now face a small dilemma...how do I do the wash? Do I just use a regular black/burnt sienna wash or do I do something different? I fear that this may be similar to the problem of painting white winter overcoats and making them look realistic.

I think I would skip the wash and just try to weather the lower areas to show the whitewash wearing off/being affected by the snow

Sounds good. Thanks Blaster!!!

my recomendation is to use future floor polish instead of water for your wash. Care needs to be taken as it is a wax, but you will get a nice blending effect over the whole model, and this works VERY well with white washes. Make sure you highlight BEFORE you use the wash...It takes a little getting used to, but works out very well.
