Check Roadfly or Autopia detailing forums. Sooner you get it off the better. If it is latex paint a wash with Dawn dish washing detergent may help. Also you might take it to a detail shop for advice or cleanup. I am sure they deal with this problem often.
Tar remover may also help. Clay may help remove small spots. However, if the offending paint is down into small crevices, a lot of work is needed.
