Daywalker, Dougums, thanks for the kind works. From you guys, that means a lt lot.
Frank, the Decals went on after a coat of future (I actually tried to use one of these spray things you use to spray water on plants - no need to clean the airbrush afterwards. Can't really recommend it - it sprays a lot of future at once... Actually using a simple brush worked best for me) with some MicroSet, and then quite a few layers of MicroSol. The decals were thick, so I could use the brush to flatten it well after the application of MicroSol without doing any harm.
Doug, the airbrush is a Harder & Steenbeck Evolution Silverline (double action). It's one of the most common airbrushes here in Germany, but think its not very well known in the US. But look here: http://www.germanairbrush.com. I really like it, easy to handle, and it gives you lot of control.
