do you guys have to sand after painting?

I would recommend sticking to one airbrush until you have more experience. Trying to learn two at once is like trying to ride two horses at the same time. It can be done, but it's easier to learn to ride on one, first.

The idea is to have fun and maybe learn something in the process.

I have to admit I don't use my airbrush all that often. I think I've done 5 or 6 models in my airbrushing career.

I have two brushes, an Iwata Eclipse and a Badger 155. I switch between them and they both behave very differently and I think that might be giving me a hard time mastering the skill. I've read a lot so I have a good understanding it's just bringing it all together you know?

At the end of the day I'm happy with my models though. 

Ayep.

Practice, practice, practice—This is where the art and craft comes in. And it happens to everyone now and then (my house is not air conditioned in the warmer months—guess what happens when I spray paint in August!)

Airbrushing is six tenths science and five tenths art. Just do the math…
