Unfortunately it wasn't intended and I've only just noticed it after washing my car for the first time in about 6 months 
It is a nasty white paint and seems fairly thick (potentially a spilt pot on a road or from a newly painted road), its splattered all over the doors, boot, rear bumper is heaped and so forth.
I've tried Autoglym tar remover and some VERY VERY old (read 10 years already opened) white spirit - can anyone suggest anything I can buy to help me get it off?
I can pick it off with my finger nail and it doesn't seem to have harmed the paintwork doing it this way but it would take days and I'm lazy!
Thanks in advance.
