Excellent guide here:

Note: If you wet-sand, you HAVE to protect it with a plastic protector, otherwise after time it will revert to becoming yellow and hazy. The yellowness comes from UV light from the sun changing the properties of the plastic within the headlight; I forgot what the material is called, but automakers use a cheaper plastic due to cost, and it reacts to UV light over time to become hazy.

Unless the headlights are in absolutely horrible condition, I think wet sanding is overkill. As I said, earlier, Novus 2 clears things up nicely. These are my 10 1/2 year old OEM headlights after a five minute polish with Novus.
What kind of clear coat product are you referring to? While it's no big deal to do the Novus thing every few months, it would be nice to apply a product that kept them looking great for a few years.

The #2 is the abrasive and does most of the work. I spray and wipe on the #1 when I'm done to add a little more gloss, but it's really the #2 that does all the work.

This is what I have: Amazon.com: NOVUS 7056 Plastic Polish Kit - 8 oz.: Automotive

By hand, using a microfiber cloth. The yellowishness and haze come off a lot more easily than you would think using the Novus #2.

You guys are killing me. YES you can polish it, like I've stated, every couple of months. Or wet sand, if they are in very bad condition. If one wet sands incorrectly you WILL come out with a bad product. I've wet sanded cars before and it's not science work, just time consuming. #1 rule) Don't burn the item your sanding. 2) Always keep water on the paper. 3) rinse off occasionally. 4) Don't let it dry out in the sun. If you're still confused then just stick with the polishing type. I can dig up an old tutorial if you pm me.
