Gentleman, crazes in headlights. Looks like tiny cracks inside the polycarbonate, mostly (only) visible from a 45° angle. You only see them, you can not feel them, they dont catch a fingernail.
They look like this:




Most shops told me that they can not repair this because it´s insde the lens, inside the Polycarbonate. I have send this picture to some companys, all denied the work and regarded these as "Beyond Repair". Also a buddy of mine how runs his own car body and paint shop told me that he cant fix these cracks.

But there is one shop in Germany wich is specialized in headlight repair wich told me that they can fix it. I became aware of this company through a story in a german oldtimer car magzine. I was impressed by the pictures of the company, the equipment and the shop looked really professional, not like a small garage bussiness. Now have a look at the headlights after the treatment done by this Company:






I am DEEPLY impressed with the outcome. The company is located in germany, the homepage is only german, but they offer international service. They have Customers all around the World, from the USA to Japan.

I have paid 330,-€ for both including taxes and shipping. Your Mileage may vary because of different cost for Shipping and Customs.
The headlights are now UV coated again and have a two Year warranty.

 

That is remarkable. I suspect they use two methods. They remove the top layer and then apply some kind of thin sealant that wicks into the cracks. They then perform another surface removal/sanding/refinishing followed by a polish. I can't tell if they apply any UV coatings in liquid form or install a film.
I would put some film on those to keep them pristine.

Thanks for the post!

 

Damn bruv, that turned out great.

Maybe clear bra wrap them so they stay fresh. I'm glad I did mine.

 

WOW!

 

That looks great... my car would look so much better with cleaned up headlights.

 

They do look good...be interesting to see how well they last...please do keep this thread updated

 

I was thinking the same. I had a Phone call with a friend, a brilliant technican, today. Among other things, we talked about the repair of the headlights. He came to the same conclusion but added that it is most likely done in a vacuum wich would help the liquid / selant tremendously to wick into the cracks and fill them. And this was the "Bingo!" moment where everything makes sense.
This company has a lot of vaccuum chambers wich they use to apply new chrome to worn, damaged reflectors of old headlights. There where pictures of the vaccuum chambers in the Report about the Company in the oldtimer magazine.
This would explain why this Comoany is the only one so far wich could perform this type of repair. All other companys could only sand + Polish the headlights.

So far, this is the best guessing about the repair process. But no matter how they do it, the outcome is great.

 

You may be on to the secret of the repair. We have an outfit in the US called Safelite that specializes in repair and replacement of windshields and other auto windows. If you have a rock chip or bullseye that is less than a Euro coin size (or quarter) they can fix it by a vacuum press and injecting a sealant. Works pretty well and makes the crack almost invisible.

 

Absolutely....Amazing!

 

Looks amazing.. anyone know of a company in North America that offers similar services?
