Hello, at a recent model show I bought some bottles of Vallejo Model Color (for brush painting) and Model Air (the one for direct use in airbrushes). I tested them on some plastic sheet with (for me) astonishing results. Model Color do not adhere well, even after a month drying time they can be easily scratched. More tests on primed surfaces, specially (alcohol) cleaned plastic surfaces showed no improvements. On the other hand, Model Air is perfect on any of the tested surfaces, not more prone to scratches as enamel paints. Has anyone of you similar experiences and what can be done against it? Or alternatively, show the Xtralicx acrylis better behaviour (haven?t tested them so far)? Any comments about this and other acrylics (to paint modern jets in
1/72) are most welcome.Thank you very much,
Martin
