I have finished a German machine gun team in camouflage, fleshing out the Waffen SS boxed set. I followed the steps on the Flames of War website. http://www.flamesofwar.com. Although the guide is for 15mm figures, it scaled up pretty well I think.
When I was painting the figures, I wondered if the colours were a bit bright. But looking at the finished models from 'wargaming' distance, I think they could have been brighter still.
I varnished the team with Windsor and Newton, using a brush. No hot weather frosting thus time, I'm glad to say.
