whoa very good price! in for 1. other kits don't include a sealant and your headlights can easily turn yellow again. great that this includes it. for first timers, you'll need a drill and i'd recommend good painters tape to protect your car paint.

Someone told me that "off" (bug spray) works as well, but for $4 (if you do the rebate) might as well get the stuff for the job

Bug spray and toothpaste are possible alternatives. See video: https://www.youtube.com/watch?v=AYmbBZntuY8

Thanks, snagged one of these when it was still available. Hopefully it will work without a ton of effort.

Oxidation is a natural chemical reaction that will occur on the acrylic surface when exposed to heat, contamination, salt air and excessive moisture. There's no permanent solution, but there are a lot of low abrasive cleaners such as toothpaste that can be used for a good short-term fix for mild oxidation (i.e., hazing) on the acrylic surface of your headlights without scratching the surface of the lens. I've used a couple of different low abrasive products like Scratch Out or Glass Wax.
