Reddit mentions of Meguiar's #10 and #17 Plastic Polish & Cleaner

I had good luck with Meguiar's plastic polish. I did it by hand but if you've got a rotary or orbital tool you can save yourself a lot of arm strain. This reminds me I've got a before and after shot here.

If you ever end up with some infuriating scratches on your epoxy countertop you can polish it out.

I do a lot of work with plastic, especially epoxy. And both of those product lines are great choices.

Never used it, but maybe this?

I've been using this on my lights and rear window (convertible). It's fantastic!

I agree. For all people to accept encapsulation, the highest priority is visibility. For my slabs, I use clear 3x4 inch plastic bags, so all the handling damage happens to the bag, not the slab. Then, when it's too scratched to satisfy me, I simply replace it. Here's a fairly comprehensive link to all the info you need to get the right bags:

• Where to find recloseable bags for slabs?
  
  There are ways to polish the slab plastic to get the scratches out. Meguiar's plastic polish is one way. Search around and I'm sure you can find other suggestions for ways to polish the slab plastic. Then, when it's done, put it in a clear bag instead of handling it directly.
  
  Check out ggoodluck2013's (new, ending, sold) listings on ebay. He almost always has something in stock that has the coins embedded in clear Lucite.

Any car wax can work. I've had good luck with this: http://www.amazon.com/Meguiars-10-Plastic-Polish-Cleaner/dp/B0002VAZ34

Just apply it like car wax, let it dry, and wipe clean with a clean soft cloth.

You should be able to find a vinyl polish at the auto parts stores, follow directions on the bottle and test a corner first like it probably tells you to.

Something like that.

Try a headlight cleaning kit.
