Here's the rest of the Pz IV (just in case you were wondering why I would be crazy enough to buy one just to cut off the gun barrel )

What did you use to make the zimmerit, ArmChairGeneral? I started trying out Testors Contour Putty, but that didn't spread out well at all. I'm currently trying Milliput (which has the advantage of being almost the correct colour, at least from what I have read) but that seems to have a very small window between being too soft and breaks up when 'contoured' with a screwdriver, and being so hard that I'll need to sue myself for "workers comp" as a result of repetative strain injury!
