I won an ebay for 2 chariots, 6 chaos knights a chaos sorcer and an exalted hero for a ridiculous £13 which I only caught because I mistyped in EBay after trying to find something else, so now I'm building a chaos army
This looks like a pretty quick and easy effect to achieve. It doesn't seem to be highlighted at all. Here are a few methods I'd suggest:
For the easiest and quickest way: Basecoat Leadbelcher / Wash Nuln Oil until happy with the appearance.
For a little more detail but still quick and easy: Basecoat Leadbelcher / Wash Nuln Oil / Dry brush lightly with Leadbelcher until happy.
If you have some more time and patience to get a better result, I'd recommend: Basecoat Leadbelcher / Wash Nuln Oil / Dry brush lightly with Leadbelcher / Highlight Ironbreaker / Wash Nuln Oil once or twice.
Yeah you could probably get away with leadbelcher spray basecoat + nuln oil (or, better yet, a vallejo alternative) + light (!!) drybrushed leadbelcher highlights. I'd probably go over and edge in a brighter silver as well, just to give some definition (i.e. along extreme edges of places where the light would catch).
Cool buy, though. Those are some oldschool 5th edition chaos warriors, which is cool to see. I have a whole army of those guys from back in the day. Keep intending to do something with them eventually.
it looks as if they mixed silver with a black wash or applied a thick black wash over a silver base, you can also add a small amount of black to silver and that may get you the same effects, best of luck
