The spiraleschnauze (some folks call it the wirbelschnauze or some such) was, more often than not, black and white. There were other colors used, blue and white, black and yellow or red...
I've only done one model with a spiral spinner (actually two spinners) and it's the Do 335 below.
I painted the spinner white then applied a mask made of a thin strip of masking tape cut so that the width decreased to a point. I applied the thinner end to the tip of the spinner and wound it around until I got the desired pattern and coverage. Then I sprayed the spinner black and removed the mask.
For the front spinner (not shown here) I did the same only reversed the colors for the helluvit. I figured that since I was putting the bird in theoretical markings (the Do 335 never made it to an operational fighter unit) and since the spiral appeared in many variations to begin with, I'd have a bit of fun with it.
There's a number of masks available that you can buy, but why spend the money on something that you can do yourself quite easily? Alotta decal sheets also provide the spiral as a decal, but I prefer the painted on look.
Someday I'd like to try hand-painting one of these as many of the originals were hand-painted as illustrated by the shot below:
I, too, would like to hear others' techniques for applying the spiraleschnauze.
