Does anyone have recommendations for some chalk that resists water very well?

I'd love any recommendations of brands, specific chemicals or properties to look for, or maybe questions that I would need to answer about the environment.

I'm planning to use my chalk on my asphalt driveway.

You could try covering it with hairspray. That's what we used to keep our charcoals from getting everywhere in art school.

It should eventually wash away, but might help some.
