For rock chips I'd apply the primer and paint with a small eye dropper, or a toothpick dipped in paint to get small drops of paint into the chip. You can overfill slightly, then once totally dry block sand lightly with some 600 or 800 grit wet, hit it with some compound and it should blend in nicely.
