I just re-read your comment and understand that you are saying damage to the inside of the lens is impossible. You were replying to my second sentence only but that was not very clear at first read.

 

Ok, good luck with it.

 

It's not the smudge on the inside, it's definitely on the outside. Just use some sand paper and sand it just like achtung described. Your headlights have some oxidation also where the eye brows are. Do what achtung described and it'll look like new again

 

do what everyone else has said...sand with the appropriate sand paper grits, and clear coat...clear coat is a must, most people just sand and buff.. thats fine, but it wont last long, clear coating it will make it look like water is on it, protect it longer and wont come back after a few months.

 

This is the first time I've heard of clear coating the headlamp cover. Never would have thought of that.

I've got the hazy look on my covers and at the eybrow too. Will have to give this a try.

Thanks for the tips.

That guy's damage was at the top of the lens only. I have that also but my main concern is the damage at the centermost part of the lens because its right in front of the xenons.,

 

I went out and bought a lens repair kit that had all the sand paper and everything. I took a flashlight and inspected the lens and I swear the damage looks like its on the inside. It feels super smooth also. Ok so I use the lube and the coarsest sand paper and sanded for a while, then on to the next sand paper down to the finest sand paper.

It looked like the damage was diminishing, but when I finally finished and wiped off the lube, the lens looked and felt exactly the same as it did before I started.

 

did you polish it after sanding?

 

Ah yep. The polish comes with the kit.
