Reaper Master Series Paints are what almost all of our painters use. They are amazing.
The armor effect you are talking about is NMM (Non Metallic Metal). There are many tutorials about this painting style online. In addition, you can see it live and in action on the Hot Lead Painting DVD which we sell in our Online Store.
I noticed you side stepped the question about mounted figures. I know you get tired of me asking,but, are there plans for a mounted line? I believe it'll be a huge hit.(I'll keep my fingers crossed)
