If you're like most people, when your expensive headlight assemblies get yellow you think it's time to buy new ones. But let me save your whole wallet with the kit. I found the 3M Ultra Headlight Restoration Kit can make DIYing this a way more easy project than you would expect. It's an incredibly complete kit with everything from the disc pad holder and different grit sanding discs, to special Trizact refining disc and quick clear coat. You don't need any special equipment, all you need is the typical household drill to do most of the work. The abrasive technology is amazing. It aggressively removes build-up and oxidation without damaging the plastic lens integrity. So whether you're working on your fog lights or main headlights, 500 grit up to the 3000 grit finishing disc will give you a professional level of clarity.

The 3M Indoor Patio Door Window Insulation Kit provides a surprisingly effective barrier against winter drafts through its specialized film system.
