I've got a friend that does customs on all sorts of six inch figures and such. I'm just getting into the basis of customizing, and wanted to start small, like a small repaint. What I'd be mostly working on is stuff like the Marvel 3.75, DC Crisis 3.75 or the Justice League 4 inch figures. My friend said to use Enamels, but I've read on here that you shouldn't use them. I mean, I trust my friend, but does it really matter if I use Enamels or Acyrillics like some tutorials say?
