I swapped out the lenses in the OP with lenses from another set of jdm lenses that had light hazing/scratches. When HID's are shining through them, they appear to be very clear.

That happened to me when I first started using the CV kit, I had to redo part of the process because the clear coat was applied too thick and they appeared hazy. That's the only thing I can think of.
I'm thinking it is CV#2. i may of applied the second coat too soon or too thick. maybe even both.

If the lights are REALLY bad I start with 800 grit, then like a 1500 grit, and finish with a 2000.

I use 3M sandpaper that is meant to be used wet or dry.

Provided you follow up with a polish that will clear 2000 grit scratches, the headlights will look great when you're done.

Also, with each grit step, go in opposing directions. Say, vertical/horizontal/vertical. It will help with identifying that you got the lens completely.

There are exceptions, but I've yet to encounter a headlight with an (exterior) blemish that couldn't be brought back. That includes some seriously nasty Mustang headlights even I didn't think were fixable.

Yes!^ I recently did my gf's tC and redid mine, using 1000 grit, 1500 and 2500 in opposite directions after every grit. Followed by some meguiar's ultimate compound, PlastX, and headlight protectant! They came out perfect!

Has anybody who has polished their headlights AND protected them with some sort of clear bra had issues with their OEM headlights getting hazy due to sun exposure? After polishing my lights, I had a shop cover my lights with a clear bra in 2010, and they still look great today.

The funny thing is, i planned on restoring these headlights and applying a clear bra to them so they would retain their condition with your headlights as inspiration. I'm probably going to give it another try and be more careful with the clear coat in hopes to get them as pristine as your headlights.

I recommend using a protectant film like Lamin-x or similar after polishing. It will help keep them looking clear, other wise you will end up re-polishing every other month, then every month. It's a lot easier then clear coating and you can get tints and colors. After constantly polishing and a botched clear coat attempt I am very happy with the film. The film also protects form chips and cracks.
