The paint chart called for Aluminium dope but I have used straight Aluminium paint before and thought it was too bright and metallic for a doped fabric, so I decided to experiment. I mixed one part Vallejo Model Air Aluminium 71.062 with one part Model Air Insignia White 71.279 and gave it a real good mix, mixing it for about two minutes so it didnt seperate when I brushed it. I hairy sticked it using a Humbrol flat brush size 5 and it gave a nice grainy texture which really looks the part. I will tinker with the mix to give a variation on the different parts.
