Try charcoal lighter. It's the same as the bug and tar remover, but a
little stronger. Just pour it on a cloth and wash the cement off in circles.
Don't rub or scratch it off back and forth, it will leave a permanent
scratch on the paint job. Charcoal lighter will not hurt the paint job on
your car while removing the cement. After removing cement off your car with
charcoal lighter, wash your car, then wax it with a scratch remover. There
may be a minor scratch on your car after removing the cement.
