@Frustrated Father: I aspire to paint rusty metallics like that. Brillant work! Thanks for the help.

@DrEvilmonki :
As far as a rusty metallic base, I like the way that these are painted: http://ginfritter.coolbusiness.org/store/product_info.php?cPath=52&products_id=230
Although, if I were to drift into an non-completely rusted base, Ritual has some great work:

http://www.coolminiornot.com/128869 (again subtle, but very nice!)
As far as stone, I kind of like the way that these are painted, but I assume that there is some technique to get the mottling (which is why I started this thread ):

@green stuff: Thank you very much for the advice.
I asked about stone (as seen in the last URL above), but also was asking about rusty, metallic bases. Thanks for all of the links.
Cyril's article (though I don't understand the text very well, even after having Google translate it) looks very interesting. The steps that most interest me are:
21: How do they get the orange spots? Layering? Airbrush?
27: What does this say? How did they get the rust peeking-through?
Thank you very much for taking all that time to reply, and for the recipes. I will have to translate them to RMS paints, and give them a try when I get a chance!
This is a really nice forum to have so many people offer so much help!
