I had a headlight burn out in my vehicle. Time to replace both I figured. They were getting pretty dim anyway. I have used the Miracle Polishing rags in the past and they do a great job, but it took LOTS of elbow grease to get the job done. It takes about 10 to 15 minutes per headlight to get them the way I want. Arthritis in my shoulders, I wasn't looking forward to the pain. So I tried to think of an easier way. Then it dawned on me . . . I have a hand held orbital sander in my wood working stuff. Maybe that could do the hard work.
