Thanks again, Wojtek! Yes, I normally wash my models first, and I'll definitely have to with this one, as there is quite a bit of release agent coating it, plus, I'll need to wash-out the sanded-off Superglue dust.
All I need now is Tamiya or Vallejo colour numbers for the RLM colours, so I'll ask Jan, as he recently obtained all the neccessary info.
Hope to get some more done on the Gustav later tonight, with a view to the first stages of painting later in the week. Will post more progress shots when I can.
Terry.
