Default Pitted Headlights

Will sanding the headlights and fog lights with 3,000 grit paper remove the UV protection? I was told that it wouldn't by a local company. They are charging me $100.00 for sanding all 4 and then covering them with a Teflon coating. Another company will then charge me another $100.00 for placing clear bra on them. Is there a risk of the lights turning yellow due to the sanding? Are these good prices?
Thanks

More than likely. However most pitting (if caused by sandblasting/highway driving) is going to be far too deep to correct by sanding. If they remove a lot of material, not only will they remove the UV coating (which is VERY THIN) but they will likely cause some distortion in the plastic.

I am a pretty picky person, so if I am given misinformation about a procedure or product I tend to look elsewhere. I suggest you do the same. The UV coating will be long gone before any reduction in the pitting is noticeable and to suggest otherwise seems misinformed (on their end).

Teflon requires to be heated to 621 degrees in order to 'stick' to your headlights and form any protection. Teflon is a marketing term that is used a lot in waxes, sealants, and coatings, but unless the part is being baked at a very high temperature its benefits are extremely limited.

The clear bra will actually do a better job at slowing down any further aging, although it won't last forever. If I where you I would look at the work down by the clear bra company, and if you are happy with the quality, then go for it. I think it is a more than fair price.

Thank you!
I will pass on the sanding and will have the clear bra installed.

I just had a client that had to sand his Viper SRT10 headlight down and spray the UV coating on it. Came out great. I then applied the new clear bra material on it. I would think they can do the lights for $75. That's what I charge and I still make a little money on it.

polish the headlamps yourself and then use a coating like Optimums Opticoat or CQuartz for several years of UV protection. Best part it can be used on paint and glass too so you can take care of an entire vehicle at one time.

Polishing or wet-sanding headlights without renewing their UV protection is a false economy, unless this protection is replaced, the end result is that you'll have to do them again in a few months (repeat this polishing process enough and there will be no material left to work with)

I’ve always been cynical of any claim that states a UV protection product has X years durability as all UV stabilizers are sacrificial, meaning they are gradually expended to where they can no longer protect against ultra violet radiation damage

One of the main influences on the UV-B protection coatings performance is the amount and type of UV absorbers used. Ultra-fine metal oxides deliver superior UV protection and significantly improved transparency and durability.
