Polishing headlight in car issues?

[RogerG55]

First thanks for letting join. 

My question is are there any issues that can come about by polishing the headlights in the car, someone told me that the module can be damaged by polishing while in the car, Im not doing it a pro is and he tells me he has never heard of that, I just want to be informed. Thanks

Most modern headlights have plastic lenses that have UV resistant coating on them.  Polishing the lenses removes that coating, causing them to "fog" more quickly in the future.  Several companies advertise they have recoating's that replace the factory, but we have yet to see one that actually works.

 

As for damaging the electronics associated with the headlights, that seems to be more of an "old wives' tale" than anything else.  It's possible that a buildup of static charge could happen which under some obscure situation could upset something, but again, never seen it happen.

Thanks I appreciate your response. Dropping the car of at the detailer tomorrow. He did say that it doesn’t last forever and eventually if I keep the car I’ll have to replace them. My plans are to keep this car long term, but then again plans can change 😂

Detailer did a great job and saved me from getting new lights for now, I know in a couple of years they will probably get cracked again, I’m hopping to keep this car a long time, but one never knows.
