My favorite things about WW II painting is the vehicles. They're a great change-up from my usual Dark Age painting and I turned to YouTube to learn weathering techniques. The variety of techniques is a bit overwhelming and I'm still learning.
T-34/85: My first tank went together fast. My mistake here was using two washes. After the first wash, I thought the tank looked too bright and after the second, it was too dark! I now prime my Soviet vehicles a lighter green to better show off weathering effects.
Lledo Diecast Truck: Pat's Wargaming with Silver Whistle blog showed us how to turn a cheap diecast into a sharp looking WW II vehicle. I bought a Lledo "Days Gone By" truck off eBay for $6. Primed black, painted and weathered up, I've got myself a transport for Mother Russia. Thanks Pat for leading the way on this very affordable option!
SU-76: I tried an improv here. I love "panel lighting" highlighs but I don't have an airbrush to achieve this effect. I tried to copy it by applying a thin glaze of light green on each panel, leaving darker green peaking around the edges. It looked pretty crappy in the early stages.
Not to worry! A wash and weathering pulled it together for a decent (if inferior to airbrushing) effect.
I've got a Rubicon T-34/76, a Warlord Games KV-2 and two GAZ trucks waiting for an airbrush. Buying an airbrush and all the things that go with it is so expensive that I keep pulling back at the last minute. Brush, compressor, painting booth, thinned paints, cleaner and on and on. With a steady hand and wallet, I'm going to make the plunge. Soon. Very soon.
