You know a place where you can buy a used lens that are clear? I sure don't. Certainly not localy and I live in Orlando Florida. No junkyards even have 6th gen civics and if any do they are gutted to just the metal.

I just tried the 1500 and 2000 grit on areas that have never been touched and i then used the Meguires ScratX which is supposed to finnish it off. It gets cloudy while your wet sanding because your taking away the plastic and making tiny scratches. The end result didnt look all the impressive even after buffing it out. It still has a shade of the cloudy look but, you get close enough and you can see the faults.
