Hi everyone I'm new to the forum...
Regarding rust faux on stucco, I have used the standard acids/phosphate type rusting agents extensively. While they work good indoors, I wouldn't recommend outside. The chemical process continues for a long time, weather affecting it for sure.
Use acrylic paints,and glazing medium- a base coat of burnt orange and begin applying multiple layers of umbers, sienna browns. Probably sponges/some ragging depending on texture of stucco.
Make a couple sample boards and play around with it...
Good Luck,
Bob
