I used the 3M kit on my 8 year old van this weekend.

I used these on shoes with clear rubber soles that yellowed and it works.

I used these guys on a set that was BAD and it worked like a champ:

The 3M kit I used went to 500. Again, looks 1000% better but still not as good as the new one.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

After car accident passenger headlight replaced. It is crystal clear. The drivers is a little yellow. I have polished it and it looks 100 times better, but you can still see a difference.
You may have to start with grit as low as 400 then work up to 2000 grit in stages before a final polish. Make sure to use a good UV shield final coat or they will be yellow again in a few months.
Maguires plastic polish is a good choice for the final polish
aha, that's why you keep your car cover on year round... Ha ha

This is what I did on a couple lenses. I wouldn't go down to 400 prematurely though if you don't have to. A lot more work once you go below 800 to bring them back to a smooth finish, especially if you don't have power tools.
Lol, actually I'm really lazy and don't like wiping the dust and dirt that accumulates over winter, especially on a black car. It doesn't help that whevener it's wet outside and I have to open the garage door, crud falls from the bottom of the garage door onto my car as well.
The 3M kit I used went to 500. Again, looks 1000% better but still not as good as the new one. My brother said the entire plastic yellows all the was through and no matter how hard I scrub it won't all be gone.
After reading these posts and with nothing to lose I am going to get some 400 and start over.
Some of the yellowing will probably be on the inside. These headlights develop a yellowish-blue haze on the inside of the lens...not sure what from, but seems to be related to excessive heat from bulbs.
Unless you pull the lens off, there is no way to get rid of it.
Your old headlight may also have some internal crazing that is permanent, but the yellowing does not go all the way through the lens.
The bottom line - they will never match exactly. It just depends on what you are willing to live with.
I used the 3M kit on my 8 year old van this weekend. The kit has 4 grades (500, 800, 1000, 3000) then the rubbing compound. Came out very nice. You need to apply a good UV sealer which also helps to finish off the surface.
Island Girl Sea Glow. I used these on shoes with clear rubber soles that yellowed and it works. You simply put these on the headlights leave it in the sun or Expose it to UV and it will reverse the oxidation process. It was invented for boats.
