I need rust

Ok try this go to your local chemist / toy store and ask for some iron filings, sprinkle or glue onto painted kit with a rubber glue leave in the rain or moisten said filings, viola rust stains on your paint, this is not a wind up it works ,a bit fiddly but it does work.
I tried it on some large scale kits a few years ago and it came out great, lord I have just remembered this from onks ago thanks for getting the grey matter functioning again zokissima

I've had pretty good luck with the Model Master Acryls "Rust" paint. Depending on the effect I'm looking for, a silver or black dry brush over it gives the right accents.

I vaguely remember the thread, and I didn't bookmark it. If I remember right and this is the one you're talking about;-You take some ordinary steel wool. Let it sit in a plastic container in a very small amount of water (just enough to allow for a short evaporation process) and let the the steel wool rust. When the water has evaporated you shake the rust out of the wool for use. Or maybe you spray the wool or dip the entire piece first. I haven't tried this method personally and I'm not even sure if it's correct. Does it sound right to you? I hope it helps. -Cheers

When the wool dries, it will become brittle and crumble. I could see you grinding this into the paint coat somehow or adhere with white glue maybe.
I've never tried it but I have seen steel rust at the kitchen sink and this seems
one of the most plausible routes to go!!!!
Good luck!!!!

It seems like the guy put a hunk of steel wool into a small jar, like a babyfood jar maybe, and filled it with water (and some vinegar I'm thinking?). When the water had evaporated, he took a stick and ground the wool up and repeated again until it was a fine fine powder. That was how it worked to the best of my recollection.

Yeah, I think that's it. I don't remember the vinegar though.But hey, why not?

I actually do something extremely different. The materials I use for rust is flour, white glue and the paint. I build the model and before painting I coat the rusted areas with white glue and pour the flour on it. I let it dry and then I paint it with Tam acrl red-brown or Mod Master's acryl rust. I try to stay away from the mod master's stuff because it looks too redish and it should be a little more orangish. I think it looks good, but if you want rust streaks, use tam red-brown. You need an AB, or I guess you could do it with heavly thinned red-brown on a brush, but never tried it. Just load it in and dilute it down a lot and just make the streaks on the model. I think it looks good, gotta get some pics up of it...

You could also try the Rustall system which can be found in the Micromark catalog. http://www.micromark.com
It comes with 4 bottles including liquid and powder and produces real rust.

Madda, yep that's the one. I wanted to check it because I assumed that you'd need alittle bit of vinegar or lemon juice or something like that, because the corrosive properties would make the steel rust very quickly.
