I purchased my car with bad headlights from a Dodge dealer. Was told by the dealer that there was no fix as this was inside and a known problem by Chrysler. I tried cleaner wax and a light polishing compound to no avail. I was going to try and split the lenses to polish the inside. Last try I used the 3M kit on the outsides. WOW! I'm a believer now. Thanks for the tip on the sealer
