Good tip, Alex!
And Dragonsinger, as the major construction material of the 162 was wood, and they were hardly used, I wouldn't think they got too weathered at any rate.
One thing though, don't paint the intake ring in the Stab colour - I've seen it done on a few models, but from what I've read in various technical books it's just a myth - apparently they were just painted in the overall fueslage colour, or left unpainted aluminium.
