I recently hit a curb while making a right turn. Here is the damage:

If I don't apply clear coat to the scraped area, roughly how long would it take for the wheel to start rusting? If I don't care about aesthetics, would it be sufficient to just to sand down the scraped area to make it smooth? Some of it is poking out near the wheel and I am concerned that it would poke the tire.
