UPDATE: Nov. 22nd 2016: Painting the Organosol for a friend on his AAR and did another spray out test without any of the Flattener (DX685) added. It comes out darker then the mix I show in the video. But it is glossier too. He likes it better then the mix I have listed.
It's worth your time to do 2 sprays out and see what one you like. Also, take in to consideration what side stripe you are going to use. It looks best when the sheen matches.
If you get any blotching, try speeding up your dust circles and or spray from further back. Laying down less material (by speeding up your how fast you paint) will solve blotching with this technique, but not enough paint and you'll loose some of the blackness.
Hope that helps. Good luck.
