I recently purchased the Vallejo Rust pigment. I've tried out a couple of different methods for achieving a rust effect. At this stage it's only on bases, but hopefully once I get this down I'll be in a position to try out putting rust damage on larger items. Anyway, here's what I have so far, please let me know what you think and/or offer advice on how I might improve:
The first two on the left I just used the pigment as per the instructions (mixed with a bit of water) and then stippled on dull metal with a tiny piece of foam.
The other three had the rust mixed with the Vallejo transparent woodgrain (70.828) instead of water. This looked okay, but a little dark. I then stippled on the (new) GW Ryza Rust and then used a sponge with dull metal as described above.
Very open to comments and suggestions.
Thanks for you time.
