The escape pods are 1 cm. square cut pieces of styrene. Thicker pieces are also added to the highlighter markers.
All parts were given some automotive primer and a basecoat of Model Master RAF Sky Type 'S' Ana 610. This color ended up being too green for my tastes. I late added some heavy weathering using Intermediate Blue, and later toned down with Light Gray. I was really happy with the new base color since it became bluer.
In the end, this weathering stage wasn't needed but was good practice for other kits in my collection.
