Yesterday I did some moulds from the classic bulkheads. I didn’t like my first idea of a bricked wall around and I didn’t want the same pieces on the outside. On the other hand I didn’t want to wait another month making new moulds so I just copied the bulkheads. When I started airbrushing them my compressor died… Crap, I went for plan B: Rust! I think it turned out quite well. I have some stuff left, corners outside doors and some cover for the wall tops.
