100 grit lol. I`d just use a wire wheel on a drill.
It`s hard to give a good recommendation because it depends how bad the headlights are. First I`d try aggressive compounding. Of course, compounds / polishes are just liquid sandpaper - so theoretically, if you have the time - you should be able to compound through most headlight damage using aggressive techniques and small pads. It`s not paint - so you don`t have to worry about burning through clear coat. Of course, if they are bad - this could take a lot of time.
I`ve never done it - but I`d think spraying any kinda clear on headlights would make them look odd and orange peeled. Of course, you could try and sand / polish that out to level it.
I`ve corrected headlights on my own vehicles that weren`t too bad using paint correction stuff. I`ve just used whatever LSP was on my paint and they stayed fine. You just have to reapply every so often.
I remember there was a thread about using Helmsman Spar Urethane as a protectant. I do some furniture restoration / wood staining. That product is an oil based polyurethane protectant with UV inhibitors that is meant for topping a wood stain on wood for outdoor use. Oil based polys will yellow over time and they are supposed to. This is not an issue on stained wood & often adds to the character of the stain - but on clear plastic or white paint it`s gonna look bad. I would just wipe them down with OCW as a protectant a few times a year and be done with it.
