My 2004 Coupe has had "clouded" headlight covers from the day I bought the car. When they were selling me the car, they said they would replace them as the problem was equally bad on both sides. When I bought the car, they said "no can do". I have the extended warranty and two dealers said they were "not covered under warranty".

I've lived with the problem but have been very annoyed by them. The rest of my car looks flawless; then you look at those plastic covers and wonder. (see photo #04)

I did buy two new light units off eBay but have been two lazy to install them and, until recently, I didnt have a house with a garage. Now I have the garage.

I decided today, since it was rainy, to try the polishing process. I bought a packet of "CV Headlight Restorer/Defogger" at Wal-Mart for $20. I had read about this product in this forum months ago. Its a 4 step process:

Step 1 involves wet sanding the light cover with a fine sandpaper for about 3-4 minutes. (see photo #10 before wiping off residue)
Step 2 is about the same, except you use a finer grade of wet sandpaper for this step. (see photo #14 after sanding and wiping)
Step 3 involves using a polishing compound -- requires about 1 minute or maybe two.
Step 4 after cleaning the cover thoroughly, you apply a thin coating of some clear sealant by wiping it on with a small patch of cloth. You wait about 3 minutes between coatings; I applied about 4 to each light unit.
(see photo #20 and #24 showing other side after it was done)

They claim, after about 15-30 minutes, you're ready to go and drive it.

Everything is provided in the package. I did not mask off my car body around the light, but that might be recommended. I worked just extra carefully.

I'm very pleased with the results; hope it lasts now.
