1600-grit polishing solutions actually work well enough to be indistinguishable from new?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.
Yet, this article says that abrasives will only work on "glass" lenses.
