Skorpsta,
I started work on this bust about 2 years ago. using the vallejo military sets, can't recall which one right off the top of My head, but I used plain old winshield washer, 2 drops of jet dry and a drop or 2 of liquidtext flow aid... I guess it turend out pretty well for a brush paint thinned out for airbrushing...
but this is what I got out of it.. used an iwata eclipse gravity feed for all that you see.. the black straps were brush painted with the same series of V paints.
great stuff I use them for small stuff now though.
hope this helps you out to some degree
