To stop the rust, I just sprayed it with a krylon sealer - worked like a charm.
My thread was archived, but the pictures don't work anymore. The thread is here: http://www.therpf.com/f9/opinions-needed-owk-grenade-weathering-508/
The two pictures are this early one:
And this final one:
Since these are 4 years old, it looks even better now. A bit more dull and an even darker grey/rust color.
Here is a shot that's more recent that give a better impression of the final effect:
I used PermaBlue to darken the frag body and brass black on the windvane. Then I wet the frag body and used a hair dryer on it. It rusted quite a bit. I then used an old toothbrush to brush off most of the rust.

I used paint on a couple of mine.
A rust-brown on one and plain brown on the other.
I then used a sponge to add black on surface.
The different textures are due to the finishes on the grenade.
The orange looking grenade has a smooth finish.
The darker grenade has a bead-blast finish.
The brass is the easiest part.
Perma Blue found at wal-Mart tarnishes brass nicely in a matter of seconds.
My weathered grenade's up for sale now, eBay item: 300232986093.

I have a spare Parks/Romans hybrid saber that I keep thinking about weathering, but can never bring myself to actually do it as I can never quite decide what I'm after as a final result. This thread might have inspired me enough to have a go!
I like both Howards and the lesternessman posted ones for different reasons - still can't quite decide where I would want to go.
Great photos so far, but what about weathering Alu? Since I am planning to use this hilt with my future Old Ben costume, was looking to assembly it with Alu parts to make it lighter , if you know what I mean. Any experience doing this?
Aluminum Black is popular. The finish, in my experience, is duller that using Perma Blue on steel. By duller I mean that it's a flatter looking finish, not as smooth and shiny. I don't think I've ever tried polishing after using AB though, so you may be able to bring back some shine with steel wool.
It also doesn't get the rusty look. It's a more even black/grey color. You could use the Aluminum Black and then use paint to simulate the rust.
Laszlo--wow, I stand corrected! That's natural weathering!! Is it essentially fine rust over and over and brushed off in between rustings? Did you heat it or boil it after all the rusting? (That's said to be one way to darken rust-browned steel).
Rebel agent--IMO aluminum doesn't look good with chemical weathering or abrasive weathering of anodized color. The only way to make it look decent IMO is a really good artful paint job. Possibly the initial grey you want to show through in 'weathered' areas might be done with aluma black but it's very hard to control and doesn't always behave predictably depending on the alloy.
Grind up some rust colored pastel chalk, spray the grenade with some clear semi-gloss, let it dry a bit, but before it's totally dry and still a bit tacky, brush your rust dust into the recesses.
You'll get a more realistic sheen to the metal, and a matte spotted rust in the bevels.
Taking notes guys, let's them come and thank you for your time!
I am wondering if after rusting the grenade to my desired state, if a coat of bees-wax would help seal it (not oily) and help give it a nice still used look?
I know this is an old thread but as I am making one of these sabers at the mo I thought I would ressurect it.
I have been in touch with a few modelmaking friends of mine that work in the busisness and they say that good old ****/urine is very good for weathering steel. That and the water, vinegar and salt method. do leave it out of the liquid so the air can get to it but keep it damp with a spray bottle or just dip it occasionally.
Acrillic paint works well on Alli but trying to rust it or acid it in anyway will just create a white type rust(not nice)
I am thinking about putting a temporary protective coating on the steel inner threading to prevent rusting the threads during the weathering process.
Just a thought.
