Hi guys,
Well, after some time off on the project, it's about time I added a little update to this thread!

Currently, I'm doing some further sanding to the boat's saddle tanks (the big bulges on the side of the sub) to give it that smooth look. Moreover, I plan on gluing thin sheets of plasticard to the surface of the hull. This will create that metal-plating effect they have on the real U-boats, once painted, it'll look more like the real thing.
