I already recommended the 3M kit based on my mate's car, but before I did my eyelids on my headlamps, here is what I did:
** Clean the lenses with a good qaulity window cleaner and then wipe the lens with alcohol to remove any residue.
1) Sand with 1000 grit sanpaper (keeping the sand paper WET so it glides smoothly over the surface)
2) dry the lrens with a microfiber towel and make sure it' feels smooth to your fingers and has a uniform wite haze across the entire surface to make sure you sanded it all evenly. If you feel rough spots or see clear areas- re-sand those spots until the whole lens has a uniform white haze (it will look horrible, but don't worry.
3) Sand with 2000 grit sandpaper (again keeping the surface and the paper wet)
4) wipe off with a clean microfiber towel and make sure the surface still feels smooth all over and has a uniform, hazed finish.
5) Mequiar's Ultimate Polish (or good quality plastic polish) applied best with random orbital and orange pad, or polish by hand with moderate pressure. Don't polish like you do wax with one coating and stop. Really rub hard and continue working the polish into the lense for a few minutes. Wipe off and repeat until the lens is crystal clear. If you aren't satisfied, or see a foggy spot, then repeat the sanding process on that area and polish it until it matches the rest of the lens.
6) I finished it off with a good coat of wax to protect against UV rays and I re-wax them when I do my car every 3-4 months. They still look crystal clear and my car usually stays in the drive and not in the garage because my 68 Fleetwood lives in there with my wind surfer, jet skis, and assorted crap.
IMPORTANT: Be sure to tape along the edges of the car where the lenses meet it to make sure you dont sand past the edges of the lens and sand your clear caot off your car body. You will get white, watery slime that falls onto and drips onto your bumper, etc. It dose NOT harm the paint or the finish on your car body - it will wash off with a spray of the hose after you're finished working on the lenses.
If you buy the 3M kit, this is basically what you will be doing - but the kit comes with a fiber ball that you attach to an ELECTRIC drill (not battery) for the final polishing.
It will take an hour or so to restore both lenses and I promise you WILL like the end result. There are YouTube videos you can watch before you do it - just search for 3M headlamp restore.
