I picked up some Minas Tirith soldiers from eBay and they were already painted. They were not painted very well, but they were cheap so I wasn't mad. I didn't want to start over so I thought I would try to "fix" the paint job and see how they looked
Below you can see how these looked when I started..
Most of the work in fixing these was just applying a better layer of silver on the armor. I did a little bit of work on the weapons and faces. Then I applied a wash to the whole model and then based them in my usual way. The results are below and I am happy with the results.
