Making my Tusken face pieces rusty?

[kibosh]

I'm using a set of resin face pieces for my Tusken I got on the Krayt Clan boards a couple years ago. The pieces have quite a bit of pitting from air bubbles in the cast and such. At first, I was going to mud over everything, and sand them smooth before painting. Since then, I decided to leave the pits to represent weathering. The desert is a harsh environment, and would weather everything, including exposed metal.

So far, I primed them, and applied two coats of aluminum spray paint, sanding each coat with 1000 grit. Very pleased with them so far.

But now I'm stuck. I've have ZERO experience really weathering anything. How can I "rust" them? I'd like the rust to be in the pits, and areas where I've sanded down to the primer. I keep reading about washes, dry brushing, etc. but I'm not sure how to go about doing them, nor if they're the way to go.

Any advice??? Any good tutorials or technique explanations?

Thanks!

I'm no expert either, but I got pretty good results on my R2--who suffered through some of the same Tatooine environments. I used some inexpensive acrylic paints- burnt and raw umber, burnt and raw sienna, yellow ochre--and dabbed, brushed, smeared, and scattered it about. Then I had a spray bottle with water handy to thin it out, wash it off, and spread it around. Then I dabbed with a paper towel or a soft cloth to remove some before it dried. As it dries you can rub and smear to get the look you want. I should think that you'd be able to get a really good look on those pieces with the rusty colors.

If you want to add some real rust you can pick up a 2 part package at your local craft store. Basically one bottle is a gray paint with iron particles mixed in. When you paint that on it leaves a thin layer of iron on your piece. The second bottle is a liquid solution of something that speeds up oxidation and creates the rust. Check out the link to the bigger photo to really see the texture you can get.

I used it for these pieces.

Keep in mind what type of materials you're using this one, don't want to run into any unexpected results. Also if you do go this path apply the rusting solution in really light coats. And give it a day or two (or more) to see how the rust really develops. The pieces in these photos are a lot more brown and rusted in some areas after about a week.

That really looks good. Any online sources to order one of these 2 part rust kits?
