Hey all, this is my first tutorial!
I made it cause the only tutorials on metal I found told you to drybrush your models. That looks well and fine, but I do it differently soI thought I'd share my way of painting the metal bitz on my orks....
First, the rusty look. I used it on these two for example:
First stage for that'd be a solid layer of a dark metal (I used
GWs boltgun metal)
Then apply a black wash, badab black in my case:
Now you apply a homebrew "rust" wash. I mixed vermin brown with little bit of scorched brown (4-1) and thinned it down to a wash. If you dont have vomit brown, a 5-1 mix of bestial brown and blood red also works (wich you then mix with scorched brown)
After that you use a sponge (or in my case a piece of foam) and rip a chunk of it off. You need a rough edge. Use that to apply some vermin brown, with some scorched brown mixed into it.
Followed by a wash of vermin brown:
Then, sponge on some more vermin brown, this time without any other colors mixed into it.
Here you go, sadly the cameras batteries died before I could take photos of the highlights I had done, but it looked like the tankbusta nob above.....
And here is the other method. It looks like old, worn metal.
Start with a solid layer of a bright metal (yes, bright. The idea is to make it darker and darker using washes, and you stop when you have what you want)
I used mithril silver:
Then, apply some thinned down badab black:
and some devlan mud:
and some sepia:
more devlan (yeah, I moved the lamp coloser o it actually looks brighter.....):
Then, I highlighted it with a mix of boltgun and mithril (wich should look look the chainmail I dont own

)
the finished result:
If you're wondering why the paint on the mithril basecoat pic looks a little thick; its because I had already done all of that once, but forgot to put a
SD card into the camera

I had to repaint both arms -_-
I hope this helps someone
