What is your favorite headlight restoration kit?

I used a 3M kit on a Honda Fit with excellent results.

I bought the 3M one before I had a DA polisher.

3M Headlight Lens Restoration System, headlight polishing kit, restore yellow headlights, 3M plastic polish

They have another similar one that I just bought on sale that also has a synthetic sealant.

I liked it because it has a backing plate, 3" pad, and several sanding dicks, including a 3000 grit. I feel the kit could use some intermediate sanding grits though.

Now I just buy packs of wet/dry sanding paper and do most of the sanding by hand and use Optimum Compound and Polish. I use Opti-Lens as my LSP.

I've heard good reviews of the McKee's 37(or DP) and the Wolfgand headlight polish, but have not tried them.
