I put my spare passenger side headlight assembly back on as it doesn't have nearly the UV damage as the one I took pictures of. So, I have polished that one in hopes from keeping the damage from getting worse.
We have started on the bad headlight lens (the whole assembly is on the bench.. So far, the roughness is gone, but not even close to removing the UV damage.
Would you mind terribly giving a step by step if you've done these yourself? It would be so appreciated. Thanks!
Cissy. you're one of my favorites-I'd be glad to help.
1. I would remove the headlamp assembly. You know how.
2. Determine the highest grit you can use to cut the remaining hard coat off. I have had to go as high as 400 to make a dent. And I did this "dry". Just go slow so you don't get the surface too warm.
3. Use this grit to make the entire surface a uniform "Milk Jug" white. As you sand, you'll see the horizontal line of the damage move down the face of the lens. Follow with 600.
4. At this point, you can use the 3M kit and instructions.
Getting through the remaining hard coat and making a uniform surface is the key to success with this job. And it is hard.
I had to use this "extreme" sanding to repair my neighbors 2005 MB E320 headlights (all 4 of them!) and it worked great. This is an always-garaged true MB car too. So we are not alone!
