I use Model Master enamels and Tamiya acrylics. Usually I base coat in acrylic and do washes and dry-brushing with enamels. Model Master metalizers are awesome too, but they should be airbrushed.

If I put the dummy on a flying model, I clear coat it with HobbyPoxy using about 70/30 gloss to flat hardener. Spray mist coats because it will eat the paint underneath. Once it's hardened it is fuel proof.
