So moving forward with this build, I've selected the cockpit parts and divided them into two categories. One - the parts that have decals to be applied to them, which will be painted in RLM 66 Dark Grey (Mr Hobby Aqueous). Two - parts that will be hairspray chipped, which be painted in Tamiya AS-12 silver, decanted into an airbrush. The grey parts will be coated in a clear gloss and the silver parts with hairspray.
Although the camo painting is a long way off, I started thinking about how to represent the mottled finish on Red 10. Most descriptions of this scheme call out a base of RLM 76 on the topside with a RLM 75 mottle over it. However, the more I look at some of these late war mottle schemes, the more I think it may have been the opposite. Here are a couple of photos of Red 10 at the time of capture. Note the overspray of the lighter color over part of the red "10".
So I want to go with that opposite approach. Establish the dark color as the base and use the lighter RLM 76 to create the mottle effect. Using a spare Bf109 wing as a paint mule, I ran a test on this idea. The wing was sprayed with RLM 83 Dark Green (Mr Hobby Aqueous) and then given a random mottle pattern with RLM 76 Light Blue (AK Real Color 76 Version 2). I also tested a few of the custom masks that I had created in AutoCAD specifically for Red 10.
This approach seems to make sense visually as well as practically since it would represent an easier conversion to a nightfighter scheme.
