Right washing my car today and probably as many of you do if you come across somthing the sponge wont budge you get your nail to it. Well as i noticed on the ENTIRE of the cars bodywork there seems to be what can only be described as pinprick holes of rust

I've never noticed this before if anyone can shed any light on this problem it would be very much appreciated.

I've tried taking a picture on my camera but it doesnt show up.
