Once upon a time I've built Trumpeter KV-2 soviet tank. It was about year ago and it was my first model painted with Vallejo acrylics. Few weeks ago I've decided to remove paint from old model and repaint it, but now in worn-out winter camouflage schame.
Thats how the model looked before "renovation":
After removing paint I thought that I had broken-off crew hatches handle bars (they were missing) and I've made them using wire. But... real KV-2 doesn't have crew hatches handles



Few words about painting process...
First of all I've primed the model with my favourite enamel black Revell no. 6 paint. Next I've airbrushed Vallejo Model Color Russian Green. Next I've added a little bit of yellow paint to remains of Russian Green in my airbrush and highlighted centres of armour plates and upper surfaces. When paint had dried I've sprayed coat of Sidolux acrylic floor varnish (Future). Finally it was the time to make winter camouflage. I've airbrushed layer of white Vallejo on part of a model and quickly started to rub it with either dry and damp (water) brush. It's somehow quite similar to hair spray technique.
Next I've sprayed another layer of floor varnish. When it was dry I've applied oil paint wash. I've secured previous layers of paint with Vallejo Model Color Satin Varnish (my favourite). Finally I've added mud (mixed plaster, soil, beach sand and Vallejo White Stucco resin) and rainmarks. Last thing I've tried on this model were MIG pigments. They are quite new technique for me but I'm generally satisfied with final effect.
Enough words, time for photos:
