Has any one used one of these?? It involves sanding your polycarbonate headlight lenses then polishing them with Meguiars PlastiX.

My headlights are a bit scratched and they've got a bit of road rash. Sanding seems a bit drastic so I wanted to see if anyone's successfully done it. On the web some people rave about it while others say you're sanding off the UV protection layer etc etc etc.

You get different levels of Mequires PlastX.

I have the 'light' and it worked well to clear up my old Juniors instrument lenses. However it struggled to clear an old corsa's headlights when I tried.

If your lenses are very unclear I would rather buy the moderate or heavy duty - then you probably won't need to sand the lenses.

So mine aren't cloudy/faded just a bit scratched and road rashed. I think I'll try just the PlastiX as a start.

It will work well for a while. You'll need to spray the lens cover with a UV resistant gloss paint for more permanent results.

I did the back yard trick.
I used Autosil (more abrasive version of toothpaste basically) and then "sealed it with Megs wax that I had at home.
This is a trick I have done on all my cars and works well for about a year, I say a year as I do this at least once a year, as a preventative maintenance system.

Turtle wax kit works well and comes with UV sealant.

When you sand, you use the same grit as used by a body restorer to polish your car after a respray. So go ahead and use the product. Afterwards there is a polishing step where you smooth everything off to a high gloss then spray UV coating over it, then polish again.

That's what I use. It definitely makes a difference

I bought Rustoleum Painter's Touch 2x Ultra Cover Gloss Clear but have not used it yet. You can sand a plastic lens with soap water, then apply PlastX and it will remain looking good for a couple of weeks. You need to spray the lens to avoid it becoming misty or yellow.
