      I used that Turtle Wax polish, and worked fine, but after 6 months or a year, the lenses became a bit yellow and blurry. What I did was to use polishing compound to restore them again, and worked fine, at least by now

The one I've been using is Bluemagic Headlight lens sealer because that's all I can find in my area. Before I started using it headlights had to be redone about once a year. Now I can go 3. I miss the days of sealed beams and new glass every time you bought lights.
      I appreciated and agree with all your comments - except the word "sand".

      It's a very fine line between fine abrasives and polishes. Even toothpaste is rather abrasive, compared to some compounds. Hand washing and use of a plastic polish will probably do the job.

      I too miss the days of glass headlights. Nowadays they would make the entire vehicle out of plastic if they could, with products lacking durability or permanence: touted as "affordable" and soon disposable, by design.

      It depends on the damage. For just yellowing polish is enough. For deep scratches it would take forever. When I've been too low on $ for a nice kit I've grabbed 300, 500, 1000, and 3000 grit sand paper at the hobby shop and stepped through them to get the job done. You still have to finish with a polishing compound to get really clear, but the lower grit (Ha ha, low at 300 which is about the highest you go with paint!) helps rip off the scratched surface, and each progressive step higher gets you a bit closer to smooth again. But ya, if the lights aren't deeply scratched your just wasting material by sanding first. A buddy of mine with a newer Lexus asked me to do his. When I took a look I laughed at him and pulled out a bottle paint prep wax and tar remover and gave them a quick wipe. They sparkled. His "yellowing" was just build up of poorly done wax jobs.

      Plastix or the Blue Coral brand works great. I've tried both and they are good.

      wetsanding the headlights is the best method in my opinion. I was buying nasty yellow headlights on craigslist for $40. and restoring them then putting them up for $150. a set. 600/800/1000/2000 grit wet sand paper. must always go opposite direction when doing so. then follow with ScratchX 2.0 and then PlastX...I do this on my aveo now too. Here's the actual right up I follow

      How To: Polish the Headlights

      the headlight on the left used to look like the one on the right. when wetsanding headlights if they start to look worse than what you started then your doing it right...

      You really know your stuff about abrasives.

      The only reason I took exception to the word "sand" is that most people think of sandpaper as being coarser than 400 grit. In other words, those who aren't so knowledgeable might end up doing more harm than good.

      In the aircraft business we use something called Micro mesh. It is a series of finer grit emery cloth (up to 12,000 grit) and it basically polishes out crazing, cracks and fading very effectively. I have crazing from a past owner using Windex (ouch)...

      I actually looked up Micro Mesh, and the company that makes it actually has an automotive Kit!

      Save time. Go right past the wax/polishes. Go right to the bodywork section. Buy the 3M headlight restoration kit. It works exactly as advertised, from lightly hazed to the worst oxidation. They will stay clear. You won't regret it. (And no I do not work for 3M!)
