I'm going to do my tiger I in a 3 color ambush scheme but I want to apply whitewash over it for duty on the Russian front. Whats the best way to apply without covering up my camo paint scheme completely.

I beleive you should lock in your camo theme with a coat of Dullcoat. You can then mix up a wash of acrylic white and brush paint it over your tank. I used an electric toothbrush, but a brush would as well.

If you don't like what you see, you can spray the tank with windex, which will strip the white wash and leave you with your base camo theme.

According to my copy of Panzer Colours, I'd go with YHR's suggestion. While only the elite (SS & Tiger II) units applied a winter camouflage paint job for the Ardennes offensive, the use of "snow camouflage was widely used on the Russian front"
There's not too many pictures in the book, but what there is looks like a watered down whitewash coat. Try a diluted coat of white paint applied with a cotton bud/q-tip/whatever you call "two blobs of cotton on a plastic stick" - I've had good results painting 1:72 scale German aircraft this way. In real life the winter camo was applied with whatever came to hand - which was usually something like a floor mop for regular army units (which is about the size of said "double ended cotton thingy" when you scale it down!).
Un-even random smearing is the best way I can describe the pictures I have, just keep the insignia clear. The book goes on to say (and show) that the paint adheasion was generally so poor that the crews could let it simply wear / flake off rather than re-paint at the end of winter.

let us know how it goes...

I forget who, one of our fellow tankers puts this on his 1/8 scale KT every winter. It goes on and comes off in realistic fashion if memory serves.

Thanks guys, I guess the dullcote would allow me to remove the whitewash without damaging the camo paintjob underneath. Great idea!

I did what Swath suggested. I used white poster paint that I just rinsed off when the snow didn't turn up

I think it's best to stick to "wading/fording" gear here in england and forget the snow camo[][]
