The headlamps on my daughter's VW had become very clouded, as the photo above illustrates, and were way overdue for a cleanup. The lamps were a perfect opportunity to test Mothers Powerball Headlight Restoration Kit (Compare Prices).
Mothers has manufactured products to help drivers clean and revive faded paint for a number of years. More recently, the company introduced sponge balls that attach to a drill for polishing those hard-to-access spots like wheels, painted body areas and headlamps.
Inside the headlamp restoration kit box you'll find a bottle of cleaner, a polishing cloth, a polishing ball that mounts to a drill and a packet with two sanding pads. You'll need to add a variable speed drill (cordless is most handy) plus painter's tape, a cup of water (if headlamps are severely clouded) and a little time and elbow grease.
