Here's some painting progress from my side.
First of all, the fuselage Balkenkreuz on this particular airplane was "toned down". The black center cross was actually painted in one of the upper fuselage colors. I had no decals to match this, so a mask was made and they were sprayed on.

After clearing that hurdle the masking and painting went forward. This airplane is one of those with "modular" paint, where the subcontractors painted segments without regard for matching patterns or colors. The following colors of camouflage are all here in one place or another: RLM 76 (the greener shade, sometimes called 84), 75, 81, 82, and 83.
