First Volume of Artifacts wasn't really for painting, just for non-glue assembly, so panel lining is rather thin.
The sub-assemblies will be those, but "priming" and basic colors will be done in one piece.
The actual first color unexpectedly is black. That's not because I want very dark for preshade for slapchop technique, but I need a glossy black base for metallics, and the metallics themselves self will be the actual preshade.
