Hi Tanker 10, I use acrylics in the same way that oils.
I have at hand several brands, Vallejo, Windsor & Newton and local ones. As diluter, to replace the turpentine which is used with oils, the Tamiya X20A.


I moisten the surface, usually a full or half panel, then I take a flat soft brush and I moisten too, I take apart few hairs and let them to take Raw Umber from the W&N tube. The rest is quite simple I let the brush fly over the surface up to get the streaks.
Then with other brush you can soften them or make runs etc.

You can do that with any colour, vertical, horizontal...etc.

I suggest to do that after the filters were applied, and before pigments. T
his KT received several filters, very diluted paint. Raw Umber, black...etc.
