Langdon,
Very impressive presentation! Thank you for sharing these important photos for the E.V aficionados here. I'm quite excited to see what a coat of copal or linseed oil varnish does to these colors.
It seems apparant from the MAG photo that the streaking is incontrovertible, as well as the test-to-failure photos of the E.V wing. It's also clear from the long-distance shot that the streaks disappear, hence the assumption that the wing was painted a solid color, usually Fokker olive.
Is there a website for Schimek where one can order these stains? It's a good bet that they're not carried by Home Depot or Lowe's.
