What causes headlights to turn yellow anyway?
There are a lot of things that can harm plastic and this is the main issue. Headlights come with a hard coat to protect them from scratches and this coating wears off with age. This is when the yellowing starts, usually in 3 – 5 years, and it is due to the environment. Soot from exhaust and other pollutants stain the plastic. Many of the DIY remedies actually make your headlights attract and hold more pollutants to their surface, like Armour All attracts brake dust to tires.
I have deep scratches on my headlight from an accident, can that be repaired?
As long as the scrapes aren’t too deep… your headlight lenses are about an eighth of an inch thick. Keeping that in mind, I have been able to restore most scraped headlights successfully.
My headlights are sandblasted after a trip to the desert, can that be repaired too?
Yes and insurers love that fact. I’ve saved them so much money that they will generally pay top dollar with no complaints.
Is there anything I can do to prevent future damage?
Keeping you headlights clean goes a long way towards preventing the damage from becoming an eyesore but they are still just plastic. I’m testing a protective covering for headlights on my personal vehicle. So far, they are doing their job.
Can cracked lenses be saved?
It depends on the kind of cracks… if they are stress fractures or from an impact. Cracks from an impact are usually unrepairable due to associated internal damage. Stress fractures or crazing can be repaired but it also depends on how deep they go. It is best that cracks be dealt with sooner than later because the will get worse if left alone. Crazing (stress fractures) is caused by using polishing compounds like “Fast Cut” and all others made for painted surfaces. I wish there were some way to convince people to stop using these products.
Why doesn’t LensDoctor® recommend using coatings?
Headlights work the way they were meant to only if the light doesn’t have any obstacles to pass through. Orange peel and streaked finishes create a huge obstacles for your headlights and defeats the purpose of restoration. Factory coatings are impractical outside of a factory setting.
Can the process LensDoctor® uses be done more than once?
The main reason my process works so well and lasts so long is that I do remove a bit of the surface. The amount of plastic removed in my process is still just a very small amount given how thick the lenses are. The number of times would really depend on how bad the damage was each time.
Can LensDoctor® remove the tint from my headlights?
For the life of me, I can’t figure out why someone would do this but… whatever. Paint or tint removal can be done no problem. I charge a premium for this, call it a dunce fee. Altering safety devices is illegal in the US and painting headlights or tail lights is an invite to the police to hassle you. If you have a weekend show car, there are better and temporary ways to tint your lights.
Can LensDoctor® fix leaks?
Yes. Does LensDoctor® offer leak repair?. No. With most headlights containing some electronic controls, I just don’t believe it’s worth it. You don’t want to cause a car-b-que.
