Okay, the stages for Judge Fear's padlock:
1. The padlock made from foam clad in Plasticard, sticky jewels for rivets and armoured plastic tubing for the top bit.
2. Based in Gunmetal.
3. Sloppy black wash applied.
4. Sloppy rust wash added.
5. Gone in with the brown i use for rust, but this time neat to strengthen the colour in places.
6. Finished with a neat colour from Games Workshop called "Typhus Corrosion" which is great for an icky, rough surface. Used that on the upper area mainly and then finished the thing with a sparing use of a bright orange in places.
