Here's mine after doing the 1000-2500 wet sanding routine:

I had used a couple different kits in the past for clearing yellowed headlights. One worked great, the other two did nothing and I can't remember which any of them were.

But I just did mine, and here's how I did it:

1. Remove lenses and clean with warm water and a tad of dish soap
2. Wet sand 150, 300, 600, 800, 1000, 1500, 2000, 2500, 3000 (no really) I used a standard palm sized sanding block by 3M
3. Rinse and Let dry
4. Polish by hand using microfiber pushing pad with "Turtle Wax Scratch & Swirl Remover" compound
4. Buff with clean microfiber pad
5. 3 medium coats with 1 minute in between using spray "Krylon ColorMaster Acrylic Crystal Clear"
6. Let dry, install

I initially just sanded up to 1000, but it didn't look smooth enough to me. Still hazy. I wanted to go much further, so I hunted down the Turtle Wax compound which is great on acrylics. I also bought a set of cotton buffing wheels for use in a drill, but after I tried them on a corner it was apparent that no change was happening after the polishing compound.

I didn't take any before pics, but will upload my after pics shortly. Needless to say, they came out crystal clear, looking brand new.

Yup, putting in a bit of elbow grease with the sanding and polishing definitely clears up the lenses pretty good.

3m sells a kit at auto parts stores like AutoZone for $30 that comes with a bit your attack in your drill and has a Velcro face with different grit sandpapers. 500, 800, 3000 and a foam buffing pad with compound and a wax. I skipped the wax and used option-coat 2.0. It's a clear resin. Should last a few years. Awesome stuff for paint once the paint is corrected to perfection. I clear coated in the past and it didn't last more than a year or so. I used a sealant and a wax and that lasted longer than the clear coat. Hopefully the option-coat works even better.

That's interesting the clear coat paint didn't last. I gave Doug Vincent my old lights that I clear coated and I think they were still fine.

Yes it is weird that it didn't last. Maybe it wasn't great paint or too thin. I've never had it NOT last forever.

Well then it was probably my poor painting skills. Painting always Pisses me off. I always wind up with a bug or specs of dust in the paint.

Try using tack cloth before painting, and setting up a little booth doesn't hurt either to keep the dust out.
