I had this exact problem on my honda civic a few years ago. Depending on how affected the area depends what to use. Mine was about 1/4 the size of my hood (accord hoods are slightly bigger). I used a product I bought at auto zone... Turtle wax! You have to peel the clear coat off until it starts getting hard to peel then apply a few coats of wax to make up where the clear coat is gone. Black is going to be quite easy because it's an already shiny color. Hope this helps!
