Heya Blowhard. That is the exact effect I was talking about. I was sure there was no filter to use as I have been trying to build them with my airbrush as well. However, my effect seems to brash (read as defined) rather than the smooth transitions your examples show. Especially where your examples show the transition from dark to transparent effect.
Too much time involved in the development of this skin to put a "shoddy" paint scheme on it. I seem to have the most difficulty with German skins so am wanting to apply myself to making the best representation of them that I can

I hope this to be the first of many German aircraft I skin.
I knew this was the place to come to

I appreciate your post sir.
