We bought for a college kid an older Toyota Camry of the early 2002-2006
model vintage where the polycarbonate on the headlights oxidized over
time
to a cloudy yellowed appearance (and the speaker covers on the rear deck
are both burned off by sunlight).

The kid has two options, of course, which is replace the oxidized
headlights altogether, or try those "toothpaste & sandpaper" deoxidizing
remedies on the net, which 'sound' maybe a bit too good to be true.

While the pictures by the headlight-polishing companies are always
impressive

Yet, this article says that abrasives will only work on "glass" lenses.

Only someone with actual experience would know the answer to that
question.

If so, which ones do you have the best experience with on Toyota
headlights?

I used this kit from Sylvania on my 2008 Ford. It uses 3 grades of
sandpaper and 2 liquids. Kit has everything you need.

There is a YouTube video showing how to use it.

It's only been 4 months now but the my lights look great.
I've used several with excellent but short term results. They look
like new for about 5 months-8 months, then go bad again. The sealer
makes 'em last a little longer
