Inherited my dad’s paint collection. These Flo-paque paints are in good condition and I’d like to use them but I’m not sure if they’re lacquer, enamel or acrylic. Probably not acrylic because they smell like the Testors square bottle paints and the label says it contains xylene so, there’s that. I’m wondering what to thin them with, if at all for airbrushing and any compatibility issues with Modem Master enamels. I know google is my friend but, not in this case.
