Awesome setup! That will do just fine for yearsssss to come 😎
I would look into the following paints Createx airbrush paints acrylic. They are very durable and take well a topcoat / clear coat.
I used myself for plastic undergrounds like a wheel cover on cars the Auto Air version of the createx airbrush paints. They can be hardened “harder” by heating them up with a hairdryer. Better for clear coats than the above.
But for a start the first ones are fine. ( they both are a thicker paint, than the following paint… but you can get used to it. If you start with createx, you can airbrush with anything hahaha)
Next look into Schmincke AERO COLOR Professional. Waterbased but a very good paint.
Also you can seal it with a top coat if desired.
I leave you the links:
Createx airbrush colours and
Createx autoair
Schmincke
I am sure you find a lot of information about them on-line.
I like both of them and use them interchangeable.
I have transparent and opaque colours and the in between ones semi.
You can get great started sets of all of them. You can also mix colours in your cup with a wooden toothpick (carefully) and add some water until the desired colours and thickness of the paint to spray.
Thanks for the tag 😁 great to be part of it.
