Not that I use it that often...
...but when I have 24 hours with optimal humidity(>/=70%). I also got low tack masking tape to be on the safe side. That seemed to work out just fine. I never did thin it though. I used the Testor's (ghetto) aerosol can style airbrush. I figured not paying for a real one for an experiment.
My acrylic paint experience mostly is from painting my mohawk with it. It took about the same time to cure unless my hair was damp. I do know once it's cured it's quite resilient. And flexible.
You should be all right with everything but I'd suggest a clear coat. All my rockets acrylic paint jobs marred easily. It almost acts like latex base.
