Nice video. I wish I'd had one of those $25 Harbor Freight buffers when I did mine :).
When I bought my truck it had one brand new headlight and one moderately weathered headlight. I went the lazy route and just bought the Permatex® Headlight Lens Restoration Kit
at Autozone for $15 instead of going out and buying all the individual stuff. The kit comes with one small rectangle each of 1000/1500/2000/2500 sandpaper, a 1oz. bottle of "headlight restoration polish", a pair of latex gloves, and a small cloth for applying the polish. I did it all by hand and got some pretty decent results.
The directions in the kit specifically said to switch the sanding direction for each change in sandpaper grit (start off horizontal or vertical, then switch to the opposite direction with each change). I noticed in the video the sanding appeared to be mostly horizontal...I don't know if that could cause any problems since I've only done it once; might be something to look into?
