They are all plastics (Airfix, Revell, Italeri). Conerning the painting, I just followed the instructions from Frank. The preparation of the figures is very important, clean them, wash them, basecoat (white) and than basic colours. After that devlan mud and finish it with some highlights. And I used also matt lack on the end to give them some small protection and remove the gloss effect of the devlan mud that pops up sometimes.
