I'm wanting to learn about using weathering powders, particularly for rust effects. What brands/colours are people using and where can they be purchased?

A good person to track down is Dean Bradley from Rails in Scale.  He has a website, a blog (http://railsinscale.blogspot.com.au/) and a facebook page.  He has some pics of some of his work and it is brilliant.  Check out his 4th or 5th article on the blog as he runs through how he "rusts" a sheep van roof.  He also sells the weathering powders.

Rust can be applied with powders though some modellers suggest it is better done by airbrushing.  However powders can be used to good effect and can sometimes also be used in conjunction with a moist surface to turn them momentarily into liquid pigments before they dry "flat" and can be sealed if required.

I use a mix of Carrs and AIM powders and have Humbrol ones on the bench but haven't been impressed by them.  They work well enough in some applications when mixed in with other brands.

The actual technique will depend upon the rusted effect I want.  I can apply a blob of powder such as AIM "Dark Rust" with a cotton wool bud and brush it out with a fine paint brush to resemble a rusted area around a water filler:

or perhaps apply a fine line of powder by using a scalpel blade along the bottom of a window frame then doing nothing more than standing the vehicle up on its wheels allowing the powder to fall by gravity down the side to represent rusting from a window frame:

and as shown here the inside of wagons is airbrushed with a suitable base colour before a more detailed application of powders by brushing to achieve an uneven effect.

I think the greatest advantage of using powders over airbrushing is texture.  Rust particularly is not a smooth surface and by slowly building up layers of powder you can achieve a rough textured surface that you wouldn't get with airbrushing.  Powders are also easier to control where they go, ie as in size and shape of the area you are weathering.

Thanks a lot for the info people especially Gwiwer... a lot of effort put into that post, thank you, I'm always stoked to see your latest photos. A combination of drybrushing, airbrushing and powder techniques defintely seems to produce great results. I dont know much about the actual make-up of the powders, so if anyone can recomend the most effective brands that would be great, preferably available via mail order over the net as I'm in country Victoria, away from most hobby shops. More techniques and links are most welcome!
