Yep, I used a Dremel tool with a really small cutting bit. Some PVA & baking soda were added for extra rustification.

Golden Gel and Vallejo( http://216.119.91.197/us/prodi.asp?pid=VAL70598 ) make crackle medium, but I like to go the hi-tech route and use Elmers glue. Essentially you put on a thin coat of Elmers and then run a coat of paint over it while still wet. The paint dries faster than the Elmers and magic happens!

This example has a brush stoke in it, but you can mitigate that with yet more Elmers & paint or add in a secondary texture with something else.

would brushing it over the glue just mix the two together?!

i have the vallejo stuff and despite experimenting, i have yet to produce a crackle effect with paint. if painted over as it is, it crackles but it's bloody clear. when mixed, it doesn't do anything

You want the paint over the glue while wet, not mixed in. I suspect that's the issue with the Vallejo crackle medium as well.

You do need to play with it a bit to get the hang of it and you can change the effect by applying dry heat like from a hair dryer on hot & low or by applying thicker paint in some areas. The brush strokes can also effect how your paint crackles. Dabs produce a different look than straight strokes etc.

A couple of quick examples here:
-The first pic shows subtle cracking from a thin layer of less wet Elmers with relatively thin layer layer of paint over the top. The base color is magenta underneath.

-The second pic shows the results from a more wet layer of Elmers and thicker, dabbed on paint over a base of turquoise. The base surface of the model was modified beforehand and given a rougher sand cast texture.

A sandblaster can be good for corrosion effects. WATCH THE PRESSURE though. You can end up with no model REAL quick if you don't.
