Thanks 🙂
I'm still quite inexperienced with airbrushing and trying things out...
Learned the next thing. Don't leave Blutack over night :x

Try this stuff instead of blu-tac, no residue, reusable and easy to handle: dersockelshop.de/pan..pression_mxa001.html

I actually might get some with my next order, thanks😉
I'm quite satisfied with blutack/patafix in all other aspects though. Seems I just have to keep an eye at the clock 😄
