So far so good. I used some fine wet and dry paper to take the waxy finish off of the leather, then some fine sandpaper.
The first greave I painted went a bit wrong, the acrylic paints I was using (two different brands) kept seperating so I kept getting dark green “pools” that made the finish look a bad attempt at camouflage. DPM greaves anyone? 
With the second greave I kept mixing the paint as I went and this seemed to help.
After the paint dried I soaked both greaves with water and scrunched them up to give them more of a used look.
The main thing I am worried about is that the acrylic will peel off. So far it is looking ok. The one mistake I did make was making the straps too small.
