Reply To: Help wanted: Dried airbrushed paint reactivating and running

[gilbert 122xp 1]

It may be (and I’ll stress the may) contaminated. I’m not saying it definitely is, but what you could also look out for to test is if citadel washes sometimes go cloudy/white in the deep recesses of a model.

The reason only airbrush paints are getting affected it thickness, I’d say. Airbrushed paints are so much thinner in application and so have loads of microscopic gaps. It’s why you can only do the hairspray chipping technique with an airbrushed paint. The brushed on paint would be too thick and will tear off in big chunks, if at all.

Maybe try experimenting by starting with a barely thinned or neet primer and see if it helps? If your other paints stop doing it you know its the primer, otherwise you could experiment with toning down (pun used wholly intentionally and utterly unapologetically) the dilution ratios of your paints or adding additional coats. All part of that hobby fun, yo.

Let us know if you solve it. Loads to try! I have to admit, I’m really intrigued what the issue is. Good luck!
