Cosmetic question

The best thing to do is sand it down if a painted side. Spray a rust preventative in those spots, then get some appliance paint. If you want a quick repair to cover them, you can buy appliance touch-up paint. It comes in small bottles, but the rust will return. So, I think you spend a little extra time here sand it down preventative then paint it. Once the rust starts, it will grow. So best to do it now.
