Airbrush Test Models

Hello all,

It wasn’t a particularly productive week, but I’ve taken a short break from painting tanks to play around with my airbrush a bit more.  First up, I am working on a 5-man Ultramarine tactical squad:

I decided to start with these guys for a couple of reasons.  Most importantly tactical marines have a lot of details but are the same color across the majority of the model.  That means a lot of surface to cover in one color, and a lot of details that need to be highlighted in the same colors.  Covering all of that surface smoothly and quickly is one major advantage to the air brush.  I started with un-primed models and primed them in black with the airbrush before mounting the backpacks.  With the airbrush I’m using a water based acrylic gesso as a primer so I don’t have to wait so long for it to dry.  Each model received two coats of primer to make sure I had a solid foundation and hadn’t missed any spots.  Next I gave them a base coat of Ultramarine Blue (Delta Ceramacoat.)  I’ve mixed the paint a little too thin so it took two coats to cover, then I applied a third over that to start creating some of the highlights.  Then I added two coats of a 70-30 (ish) mix of Ultramarine Blue and a sky blue, and finally a coat of 50-50 Ultramarine Blue and sky blue.  This has created a nice gradation from the black/near black recesses to the lighter blue across the top surfaces.  It’s hard to say how much time I spent painting vs. mixing paint.  I also re-painted the first one twice before finding a mix I was happy with.

The reason I chose Ultramarines over another chapter is that I have been painting my Rebel Grots with blue robes so the techniques and paint mixes I used for the marines can be directly reapplied.  I have 20 conscripts that will need to be painted soon and I plan to add more infantry in the not-too-distant future, so being able to base coat and partially highlight them quickly will be very helpful.  I used one of my conscripts as a test model to develop a process:

Overall, I am happy with the progress I’m making with the airbrush.  Although I would hardly be proud to call my test grot a finished model I do think it passes for a low table-ready quality.  I would be very happy to get a squad from bare plastic to this level in about an hour.  All that’s left is to pick out the details, highlight the skin and other details, then a wash and I think it would be finished.

So far I’ve been very happy with my airbrush.  I think it’s a fantastic tool for model painting!  How many of you have given the airbrush a try?  How did it work for you?
