I have heard that sanding headlights can lead to further damage..... Anybody know for sure on this?
Here's some feedback for hand application. by no means expert advice, but we may get some. (I have only used sandpaper 4 of 5 times and not sure if the way I used it is gentler than UC or would appropriate prior UC.)
I followed the directions I found here on the forum to the letter in terms wetness (can't remember the directions at the moment).
I applied virtually no pressure as I began sanding and as soon as the surface felt slippery I went to the finishing paper and did the same thing. The paper did all the cutting and my touch felt so light it seemed like I was only taking the "fur" off the plastic. Then I used the UC.
Prior to this, I had used just the compound, but even though the abrasives were much smaller than that of the paper, the finger tip pressure needed was much more than I was comfortable with and "trial and error" wasn't an option with plastic..
Got good results compared to muscling the compond which gave me no feedback as to whether I was overdoing it. As an experienced newb, Scratches can be caused by pressure, regardless the product used. That from minimum experience with UC.

"Further damage" would likely be from UV damage. Headlights will have a UV protective coating over them, which sanding, or other strong cleaning will remove.
However, if the headlights are badly deteriorated already, the coating is already gone anyway.
After you do your cleaning, you just want to be sure to keep cleaning/waxing them or using the Headlight Protectant, etc so keep them in good shape.
