Airbrush Woes

Had some time off work recently, so whilst Mel took the little miniature to various baby groups (I believe dancing and singing is involved, which is why she does it rather than me!), I decided to get out the airbrush and get some camo on those Panzers and Stugs that have been half finished forever.

It did not go well...

Even using VJ airbush paints, the result was far too speckled to be usable.  Unfortunately re-doing the base coat only made it worse:

Oops.  Good job I only practiced on the one Stug!  Back to the brushes then (as shown in the test on the left of the photo).

Still not sure how to rescue that Stug though...
