Unfortunately that does appear to be CC damage. I bet it was just a thin spot and your not-too-aggressive approach *was* in fact too much for it.
IMO (and IME as I've done stuff like that before myself), nothing will really hide it and you oughta lust live with it until you get the paintwork done.
And no, I don't think you'd like the result if you were to rattle-can it
