I'm looking for a source for acrylic panzer gray, panzer green, and mustard - schwartzgrau, olivgrun, and dunkelgelb. I see (via an ebay search) Testors has them in 1/2oz jars for $3 each. Ideally, I'd like a recipe from someone who has mixed them using the ubiquitous 2oz acrylic craft paints. (especially since the shipping is $7+ from Canada)
