If they are very, very fine scratches, ie, if your fingernail doesn't catch on them, then I'd try a good quality Pre-wax, swirl remover, then wax, should cover a multitude of sins. My favourite products are Turbo Wax.

Really important to use clean cloths when you apply the steps, allowing noted time to cure, before removing, and ensure that you don't apply or remove products in a swirling motion, straight lines either up or down, and gently.
