Used 1000 grit, 1500 grit, and 2000 grit wet sandpaper with plenty of water running over it at all times. Then got a 2.5" foam buff pad to put on the end of the power drill (cordless isn't fast enough and battery never would have lasted) and used Meguiars #17 Cleaner. Did three coats of that on cool lights (in the shade at 72f) for about 1 minute each coat. Then stepped up to finish them off with Meguiars #10 Polish with three coats of about 1 minute each. They look absolutely fantastic and better (no shiat!) than new. Now I've got to wash the car cuz that crap flew all over the hood and front bumber. I'll have to dig up a before pic and post that with the results.
For those that are skeptical of the results, don't be. I was too, but I've proved myself wrong. Don't waste $100+ on a new set of headlights. Just use that money for beer!
