I too brush Future. I also hate cleaning it out of an airbrush and it gives me several problems:
- Orange peeling when I do one heavy coat
- it turns my models into sand paper when I do multiple light coats.
I have gotten better results airbrushing at the lowest pressure I can and doing two semi heavy coats, but I find it easier to just brush the stuff. I clean my brushes and airbrush with Windex.
