Update - I have primed the various body parts and airbrushed them with decanted TS-47 Chrome Yellow. A warning to those looking to decant - let the paint gas out for about 1-2 hours before using! This sprayed very well after adding a small amount of lacquer thinner. I waited about 1 week, then applied masking tape for the green portions. I didn't have a template, so I used various reference photos and tried to get the curves correct.
I decided not to use the decals for two reasons. One reason was that I used up the green livery decals from my previous aborted build, and secondly I prefer the consistent coverage of paint. I used decanted Tamiya Park Green which airbrushed very nicely. I had some bleeding on the masking line, but it shouldn't be too noticeable.
Monococque pictures to follow. Surprisingly I didn't get any over spray in the cockpit, just leftover residue from filling and sanding the bottom half of the monococque.
I have applied BMF to the undertray and glued the engine and radiator ducts to the undertray as well.
The next step is to work on the rest of the bodywork and apply the decals.
