I’m working on 3mm scale 40K figures, as well as proxies from Vanguard, which I plan to play using their own partner system “MicroCosmic.” It’s an elegant little system. I also got an airbrush for Christmas and it is basically the greatest enhancement to my gaming life since I bought a game table three years ago. Really a great amenity! Basecoating is wonderful – you get really lovely cover and a tight, smooth surface I never had before. Great rendition of detail. And no VOCs, either!
I actually find it relaxing, rather like cleaning a gun. Which you may or may not know about. But it’s a precisely made piece of equipment, and with proper equipment and cleaners, it doesn’t take any more time or effort than properly cleaning a brush, really.
I’ll add this though: it’s taking a lot of practice to learn how to prime with it, and as I’m painting a lot of 3D prints which (as it turns out) are very slightly porous, this is a necessity. I discovered this fact after I unthinkingly dropped a handful in my cleaning bucket and they came out all soft and floppy, although they look like they may re-harden as the cleaner evaporates out of them again. Lesson learned.
Regardless, white primer is a bear to apply, I’m finding. Black primer is more successful and the survface is very tight, but I’m not certain it will give me the vibrant colors I want in my base coat, but I’m trying it anyway.
