Next I decided, since it's a mule-build, to try creating stretched skin effects. No matter it's only 1/72 and these effects are usually reserved for larger scales. I wasn't going to waste my precious time scraping plastic away so I simply created the bumps by using Mr Surfacer over masked-off ribs, frames and stringers and sanding everything smooth when dry.
I estimated that adding some drops of AK RC 330 Japanese olive drab laquer to Mr Surfacer 1500 Grey would get me a reasonably match for RLM 02 - and it did.
Next the model was sprayed in Mr Hobby Aqueous RLM 75 and RLM 83 (sic) over RLM 76. Or so I thought! I accidentally grabbed the RLM 74 bottle, so I had to respray the grey. With H&S airbrushes being prone to tip dry, I use ample thinner and about 20 PSI pressure. I was able to hand spray demarcations and mottle and for my first airbrush job in nearly a quarter of a decade, I could've done a lot worse.
As the photos aren't great at showing off the stressed skin effects, I've uploaded a video: https://youtu.be/9hkvoJq6l4w
Next will be the various details, which is what I'm currently working on.
