Had this on my white focus mate, bought myself a claybar and went over the whole car with that and removed them all! Very time consuming mind you but well worth it, paintwork comes out smooth with no spots!
Autosmart tardis for organic removal (tar etc) and auto finesse iron out for inorganic (Orange dots. Railway dust etc)
If you're lucky, you might not ever have to clay again!
