So now some more work has been carried out on the Thunderbolts. The green has had a coat of Catachan Green/Charadon Granite 50/50 mix, then been highlighted with Catachan Green followed by 50/50 mix of Catachan Green/Camo Green. The grey has received a coat of Codex Grey, which I found easiest to apply in several thin coats to get a good coverage, followed by highlights of a 50/50 mix of Codex/Fortress grey and finally pure Fortress grey.
The nose has been painted Scab Red and highlighted with Blood Red, and the tail has had a coat of Iyanden Darksun, then Bad Moon Yellow, and a highlight of Bleach Bone. The cockpit canopies have had a coat of Necron abyss for now.
Next weathering, highlights on the canopies, paint the bombs and then decals and basing.
