Here is another shameless plug. I was at AutoZone the other day getting a new battery and brakes for our Sable. While there, I spotted this gem on sale and wondered if it would work as well as advertised:

So I put the kit to work. Here is a "before" shot:

You will notice that the lens is very fogged from oxidation, abrasion, and UV damage. I spent about 15 min. per lens (it is a 4 step process working down from rough abrasion pads to progressively finer pads, finishing with a buffing process) and this is the result (on the other lens):

This whole kit was by hand. If I were to do it over again, I would have considered a kit with a power tool attachment (to get the deep nicks and scratches out). In all, for $8.00, I think that the results are impressive. High-five AutoZone!
