Hmmm - there's a couple of ways you could probably do this. Take some fine grit rubbing compound from 3M and that should take it all off. Or, you can soak it in Bug&Tar remover and then go over it with a clay bar after. Take your time, it would not be the best idea to try and force the stuff off.
Edit - My best advice would be to call a local Auto Body Shop. They'll know exactly what works and it might save you some costly damage. That's the best plan. Go do that.
