I (somewhat foolishly) bought a huge collection of Vallejo Game Color paints (new formulation), relying on the brand's established reputation. And the paints are actually amazing when they work.
However, I'm struggling with bubbling, especially when applying the base coat on uneven surfaces. The issue is more prominent with brighter colours, like bone white or light greys, but affects all paints. I'm not thinning the paints, using slow brush strokes, not overloading the brushes, etc. Tried adding some flow improver/thinner - it seems to help a bit, but makes the paints quite runny.
Has anyone had any success with this?
