As I'd taken off my old top cowl to replace it with a new one, I took the opportunity to rejuvenate my original headlights.
The previous owner had tinted these blue - and over the years the lights had gotten a little stone chipped too.
First I wet sanded with 320 grit paper, to get the blue tint off and make sure the stone chips were all smoothed out.
Then I went to 1000 grit wet sanding, making sure I'd gotten all the coarse scratches out.
This is what it looked like at this point:
Next I went to 2000 grit, but had difficulty making progress fast, so I got my Porter Cable Polisher & glued a 6 inch round piece of 2000 grit paper to a polishing towel...
Looked like this after around 15 minutes (Per headlight):
Then I took another polishing towel designed for use with the polisher, sprayed some glue on it and attached a 4000 grit 6 inch disc. This was to take the finest scratches out. Took around 25 minutes per headlight.
After that, I used a foam pad to polish with rubbing compound, then another foam pad to finish with a cleaner polish.
This is the final result:

This technique also works well for dulled / yellowed car headlights.
Best use a polishing machine such as a Porter Cable Polisher - or you'll burn a lot of time & elbow grease!
