Oh, it's awesome. Completely takes the guess work out of thinning the Vallejo Model Color paints. With the old thinner, some colors could be 1 to 1, while others could be as much as 5 to 1 thinner to paint....was no real standard ratio.

This new stuff...2 to 1, pretty much every color, and you are golden. Few of the heavier pigmented colors maybe go 3 to 1....but still...much easier to thin them with the new thinner, than the old thinner.
