New to airbrushing, new to acrylic paints - HELP!

Hello,
I finally got my own airbrush (Badger 175) and a compressor. I used
exclusively enamels before (and brushes) and now I decided to use
acrylic paints for airbrushing. I purchased some basic colors for my
first model of a car (1/24) from Tamiya and Model Master Acryl(the new
formula). I tried to use my airbrush finally and paint the dashboard in
semi-gloss black. I didn't use a primer, I washed all parts. I thinned
the MM paint with Polly S thinner and sprayed the first mist but it
behaved just like water, forming large drops of water on a surface!!
Could anyone please point out any mistakes that I made? Should I ALWAYS
use a primer for acrylic paints (that wasn't the case for enamels),
even for the smallest parts (like suspension elements etc.)?? Maybe the
paint was thinned too much? Maybe the thinner wasn't the right one? But
all the brand thinners are so expensive and it seems they are all based
on some kind of alcohol! Is there any substitution?
Any help will be appreciated!
ps. when I tried to airbrush with Tamiya XF-16 Aluminium everything
looked fine (there was no adhesion problems!). I am perplexed!

You mean it's beading up?
You probably overthinned the paint.
Or perhaps the paint had settled, and you didn't shake/mix it enough before using it, so what you poured out was mostly thinner. If there's any gunk at the bottom of the jar, you have to loosen it up with a stir stick and mix it back into the paint until it's all smooth.
I use windshield washer fluid, or sometimes rubbing/isopropyl alcohol.
Which rules out the possibility that the parts weren't clean enough.

You were right - it was WAY overthinned! Once I got the right ratio the paint looked great - wow airbrush is like a giant leap in scale modelling (compared to a brush). Now it's time to experiment and learn the art of paintbrushing. Really exciting!!!!
Thanks for your help!

Yes...you will find it is all a matter of "tinkering" until you find something that works for *you*. There is no real "etched in stone" answer.
Also, don't limit yourself to "model company" paints. Many people are getting excellent results from the myriad number of "craft" or "artist" acrylics available from places such as Michael's or Hobby Lobby.

Piece of advice: Go to your nearest Michael's and buy a small bottle of "Liquitex low viscosity acrylic airbrush medium". I think that's the correct name. you add a few drops when thinning the paint and it helps improve flow and delays drying at the tip. I found I can even airbrush the older Poly-S paints with the use of this additive, and they were formulated for hand brushing.

I'd like to expand on that: you can get very good results with watercolour or drawing inks, particularly the gray/sepia/ochre range, for all weathering and panel line jobs.
