Restoring Cloudy Headlight Lenses on a 2005 Sierra telegra.ph

Once you've completed the final sanding step (typically 3000 grit), the lens should feel smooth but appear matte. Now it's time to restore the gloss. Attach the foam polishing pad to your drill and apply a dime-sized amount of the included plastic polishing compound. Work the compound into the lens using moderate pressure and consistent motion, keeping the pad moving to avoid heat buildup. You'll watch the transformation happen in real-time as the matte surface gradually becomes crystal clear. Wipe away excess compound with a clean microfiber towel and admire your work. The clarity should be dramatically improved.
