I just used the Turtle wax clear coat repair kit. I was pleasantly surprised. Not perfect, but visually 'better'. Still can buff/polish it out more and improve it. Just have not had the time yet.
Can't vouch for any other product.

Turtle Wax products are, in general, considered to be low-end, compared to the products used at the professional refinishing level.

Something like 3M Perfect it 3000 polishing compound, followed by a protective wax should do well. If the scratches are deep enough, some light wetsanding with extremely fine sandpaper, 3000 grit, for example may be necessary. This would then be followed by the polishing compound, then wax.

Not to disagree with Russ, but I had very good results with Turtle Wax's headlight polish. YMMV
