Smile Plastic Polish?

Hi guys,
I want to polish the surface scratches out of a couple sets of clear lenses (front turn signals and back up lamps) for my 69. Anyone got any helpful hints or know of any useful products?
Thanks.

Simichrome polish works the best for fine scratches.

Simichrome works great on plastic.
The tubes are too expensive for what you get.
Buy the small tub and it will last you about 50 years.

I bought the plastic polish kit that Eastwood sells a couple of years ago, and it works fairly well on tail light lenses, which I have done several sets of. I still have a lot left of the 3 bottles you get. Chumley

Since no one else has mentioned them:

I personally have used Meguirs PLASTX on a couple of tail Light lenses. Got it at walmart. It does do a good job of cleaning grit and grime off (in my case there was greasy dirt and some rattle-can overspray mist that was on the lense). There was a slight bit of fogging that it also took care of and left a nice smooth shiny surface. That size bottle will last a while if you are doing it by hand too. Forget it if there is anything more than light hairline surface scratches though.

I had found a thread at one point, where somebody was asking about some craigslist guys that were promising to remove the frosted yellow tinge of your headlights. The OP was asking what products they most likely used, since they're pictures were quite compelling. I believe the final consensus was that they were using this stuff:
#17 MIRROR GLAZEŽ CLEAR PLASTIC CLEANER
and
#10 MIRROR GLAZEŽ CLEAR PLASTIC POLISH

Here's a link

Never used it myself but the pictures were awesome and the reports in the thread made it sound pretty "industrial grade".

Deep scratches may be a whole other story. If you've got lots of time - I too have used wet/dry sand paper method to polish copper blocks before and the results are literally a mirror finish. Start with 800 grit then 1200 grit with water, and then finish with 1400-1600 wet (such high grit is sometimes hard to find in stores though)
