I just picked up a informational flier from W&N on their line of watercolor mediums. It states that the blending medium slows the drying time and aids in blending. It was discussed in my paint pallette thread that this does indeed work with acrylics. I noticed Ox Gall Liquid improves flow and increases wetting. My question is does this medium work with acrylics and if so would a combination of Ox Gall and blending medium cause good or bad results?
