It's beautifully hideous!

I finished my Slayer and various Bonejacks.

OH MY GOODNESS!

I went a little heavy on the Bonejacks, so much so that the rust obscures the colours. However, they look like "exquisite corpses". The Slayer Warjack though. I did a lighter coat on him. He is now the most beautiful model I've ever painted. Under bright lights, you can see the differentiation of colors. The rust effect has the most wonderfully organic quality. I'll need to touch him up a bit, but he is so wonderfully dirty and gross. As soon as I can get a good picture, I'll post it.

The rust method is worth a try.
