Painting for an aluminum effect

[Bravo Six]

I'm wondering if anyone has a recipe to share for painting aluminum? I have some trash cans and a chain link fence in my paint queue. My usual go to for metal, like gun barrels and swords is:

Vallejo Gunmetal Grey
GW Boltgun Metal
GW Chainmail
and if it's a sword, I usually end with GW Mithril Silver

That said, I don't think that recipe will give me the desired effect. Any help would be appreciated.

Silver with a bit of white in the mix would do

Or even silver with a bit of grey-white. There are of course dedicated aluminium effect paints for the aircraft modelling scene.

Thanks guys, that's helpful. Here's the basic idea of what I'm hoping to do with my own kit...

Remember, it doesn’t rust 

It corrodes though and a little speckle with an off white would probably do.

But James.....rust is SO much more dramatic.

At the risk of repeating myself, I was going to suggest Revell Aqua Color Aluminium, which is magnificent for bare-metal finishes, e.g. aircraft, for a water-based acrylic paint. I've painted it straight on white and grey undercoats as well as slightly darker metallics (polished or oiled steel, usually), and it is my absolute favourite "silver tone" for pretty much any application.

That said, as you are looking for a weathered effect, I would attempt an intermediate steel tone, e.g. a mix of GW chainmail and Boltgun Metal, drybrush it with a very dry lighter silver or the VMC Aluminium paint, which dries rather white-ish, and then wash the whole thing with a mix of Boltgun Metal / gunmetal, some black and some brown ink to tone it down, overall.

As said before, aluminium doesn't rust, so you are looking more for crusty rather than rusty, with maybe a slight layer of grime on it.

Thanks Chris. Maybe the fence in question is galvanized as opposed to aluminum.
