Maybe a rookie question, but wondering what kind of paint you used for the cockpit and the rest of the interior?
Cockpit was hand painted with Vallejo paints. Mainly Luftwaffe Uniform Grey, Black, Deck Tan, Ochre Brown, and White
The floor and walls were mainly Luftwaffe Uniform with Black for some of the instrument panel looking things.
The seats were Ochre Brown
Deck Tan was used for those "padding" looking things around the doors
I normally prime things with a primer, but in eagerness to get started painting and not waste time masking the canopy for priming I just went straight at it with the Vallejo paints.
For the exterior though I masked off the cockpit and primed it with Mr Surfacer grey primer
Then I airbrushed a mix of Tamiya Sky Grey (XF-19) as a base and added some Tamiya White (XF-2) and just a bit of Deck Tan (XF-55) basically mixing to try to match the paint color on the cockpit (the rest of the body that was that base off-white color was actually just bare plastic with a wash).
If you do not have an airbrush, I think Tamiya AS-16 is actually a close spray can match to what I mixed up as well as the paint color on the cockpit. I would have used it myself, but had run out and did not want to wait for a new can
The darker grey panels were hand painted with a paint brush using various greys from the Vallejo modern US jets paint set. Things like Dark Gull Grey and Airforce Light Grey etc...
The yellow and red I originally left the original paint and just masked those areas off, but then I went back over them with Vallejo Flat Red and Army Paint Yellow later on
The engines were also hand painted with a paint brush using Vallejo Gun Metal and Natural Steel and Oil Steel in a few select parts
The whole thing was then weathered with oil paints (Black, White, Burt Sienna and Raw Umber)
