My T100 has the original headlamps (170,000 miles) and they are VERY cloudy from years and years of weather and miles.. New ones cost about $175 each but the guy at the local auto parts store suggested trying a product to restore them for about $20.. eBay has tons of products saying they are the best, has anyone ever restored headlamps?? Can anyone suggest a certain product that works? Does polishing compound work? Thanks!
