The plastic lenses on my 98 Ford Expedition are clouded up. Do any of the cleaner / polishes sold actually work? I need better light, but can't see spending $125 ea for new housings. |

the plastic is polycarbonate. when made, there is a thin protective layer, preventing oxidation. when that layer wears off, the polycarb oxidizes. they can be polished, start with 600 grit wet or dry and work up to 2000, finishing with rubbing compound. then to protect, 3m makes a film that can be applied over flat or nearly flat lenses. or you could try clearcoat. |

Found a site called 1A Auto that has a pair for $55 with free shipping. These are new with a three year warranty. May just say hell with it and order them. There ya go! Resurrecting old polycarbonate is a short term fix at best anyway.....  True, but if the budget replacements aren't UV coated they'll go just as fast as the polished ones. The 3M kit is supposed to be good if used correctly, but haven't done it myself (a pro bodyshop guy I know says they're GTG) |

Just did the 3M kit on my car. I had one headlight replaced after an accident and the other was hazed over pretty good and looked pretty bad next to the new light.
It worked exactly as advertised. It was impressive. And easy. I told a friend about it and he couldn't tell which was the new and which was the old light. Here is a video: http://www.youtube.com/watch?v=_t1RBw0IGXA |
