Yes nasty. Just carefully rub it down treat with some kurust, allow to dry, then paint on zinc primer, then when dry touch up paint.
I've got some tiny bubbles from chips on the leading edge of the rear door, I think the front door sits too far in, so the edge gets chipped by road stones. Although I think mine has had the door painted at some stage, so maybe it's a bad repair.
