Yes. Coca Cola is caustic and has been known to produce positive results if poured on a corrosive battery cable.

Yes, almost all carbonated beverages contain carbonic acid, while citrus flavored sodas also contain citric acid. The acid in Coca Cola is powerful enough to potentially ruin the clear-coat finish on an automobile. Fortunately the hydrochloric acid in the stomach is far stronger so that sodas may be consumed safely.

Coca Cola is not caustic, but it is corrosive. Coca Cola has a ph of about 3, which is due to both phosphoric and carbonic acid (from CO2).
