what is the best mixture for rust?

I agree with all who say to use rustall, especially the comment montanacowboy made about using a black base coat, it works very well

Just use pastels (chalk pastels) myself. Scrape some pastel into a powder with your knife: I normally use mixtures of brown and orange. Then, add a drop of turpentine, white spirits, or even acrylic thinner into the powder and mix a runny "paste". Apply where needed and done ! You can even build up texture where needed using this method. Apparently those weathering powders work a treat too ... haven't really tried them, so wouldn't know :-)

Nice work on the above armor, Jeff! Have you ever used the RUSTALL product line and if so, how did it compare to the MMP weathering powders?

Patels are an excellent way to go, they have texture and come in tons of colours.

Ryan-just use a rust colored chalk or scrape some off a car. ;-)

Woah! MMP powders are too expenisve for me. I'll just stick to using Doc O'Brein's and pastels.

You can get MMPs from here (:) and your local hobby Shop :), well some :) )

Ive posted this before but since the topic came back up again here it is again. I made some rust with steel wool. It's alot of extra work and MUCH MUCH more messier (hey doesn't he play hockey ) Trust me, go with the MMP powders or paint instead.

here it is on a railroad car

What is MMP Rust weathering powder and where can I buy some? (And please don't say from my local hobby shop)

Depends on several factors, but for armor and aircraft exhausts, I'll paint the part with rust red (and color basically), then, while it's still wet, apply MMP Rust weathering powder. Works like a champ.

I use the Rust color which most lines of paints seem to have - As I prefer enamels I have Rusts by 4 different mfgs (MM, Testors, Humbrol and an old bottle of Pactra). Each is a different color actually (varying from all most chocolate brown to an all most orange) and by using the darkest for the oldest rust and dry brushin with the lighter colors to represent more recent rust.

If I'm doing the exhaust system on a vehicle (and depending on how much rust and damage I want to represent), before I paint the item, I will poke, jab and grind with an exacto knife and a Dremel tool to get the bends, creases and holes that an older exhaust system will get in it. Then I paint it in a darker rust, and then while it's still wet, sprinkle it (or roll it in) baking soda. After the base coat is dry, I will again dry brush some areas with lighter colors of rust. I usually finish by painting the holes, gouges etc in flat black to represent the exhaust gas leakage. Works out fairly well.

And though I've never tried it, I would assume that Acrylics from various mfg's also vary as to color and will also work in the same way.

Use rustall on a black basecoat to achieve a rusty appearance. This can be found in the railroad section in your local hobby shop.
