Isn't that what the old washes were (nearly
all commercially available washes, actually)? Ink in water/acrylic medium with a bit of surfactant? If the medium is acrylic, water
should thin it just fine (up to a point well beyond 1:1, at least).
Spotty and/or chalky finishes to diluted paints/washes are frequently the result of the medium being stretched too far, causing pigment to clump (same thing can happen with the old paints/washes, but usually takes a lot more thinning to become an issue), in which case adding more usually does the trick. Have any acrylic medium,
OP (I imagine a pot of the new Lahmian Medium would do the trick, if you're buying
GW, exclusively)? It almost sounds like they dropped the ratio in the new line (as a greedy cost-cutting measure, some might say

)...
