Hi Dave --
That's most interesting. The H is a single-action, internal-mix type? I used to have a single/internal Badger 200, that was my first AB. The VL is dual-action/internal, which is supposed to give you more control options but initially I found it overcomplicated compared to the Badger.
I've been working with Tamiya acrylics and have not had a terribly good experience. My experiments were along the lines of super-thinning and varying the pressure, which is almost the opposite of your approach. I'll try minimal thinning and much higher pressure and do a test-shoot on card. If I can get enough control there's a Tiger tank been waiting for her camo overspray for ages -- I painted her up months ago but got too heavy a result and recently resprayed her to dark yellow.
Conversely, enamels seem to offer better control with less of a fight. The chemically 'hotter' paint seems to agree with the mechanics of the AB. I'm not game to try feehanding just yet, but I'm sure I will eventually... Maybe in 1:24 for the coward's way out! I've been intending to do a 109 E4/7 in North Africa markings, and have been thinking of doing the wing mottle through a pre-cut softmask, every olive patch cut from a single wing-sized masking card. It'll be an interesting experience...
Now, gotta spray some teensy bits of decal film for the internal canopy bars on the Emil, and start masking the landing gear bays...
Cheers,
Mike
