best way i would describe it as is millions of extremely small maybe the size of a pin hole (well, the hole you put thread through lol), they are underneath the clearcoat, but when you rub the paint you cant feel them, and yes as dom said they do disapear for a second or two after you press them, i have tried to get a pohoto but they are just so small my camera cant pick em up, i really hope a machine polish will sort them out :/
