Unless you have clear coat failure (no more clear on top of the paint), you should be able to get the paint looking like new. Repainting is tricky, cheap paint jobs are worst than living with some scratches, expect to spend a few thousand for a good paint job.
Frodo, iron removers basically dissolve small bits of metal imbedded in the paint through oxidation. Clay bars try to pull them out, iron removers kind of melt the metal away. But it's a heavy duty chemical, and needs to be thoroughly washed off any non-paint surface and the paint within a few minutes. But if you're doing a once ever ten year paint correction, it's worth the $20/bottle.
