Weathering the Brawa Telephone Signal - part 1

Did a bit of drybrushing with Tamiya Gun Metal (X-10), after the 3 coats already sprayed a while ago. Perhaps another small session of drybrushing would be in order. Also i'm thinking of a rust color wash. The small bit of masking tape will eventually have to come off, since that big F will also need treatment. Click for a larger photo.
