I noticed a browning on my driver side headlight. It looked like the outside, so I used headlight restoring compound but it didn't go away.
Does anyone know how this happened and how to get rid of it?

 

i restored my headlights a few weeks ago.looks brand new. https://www.amazon.com/SYLVANIA-3877.../dp/B00429NKWK

 

I've been using the Meguiar's cleaner, which always worked. But this one just isn't coming off.
I don't even know how it got there.

 

I just restored my headlights the right way. I just bought the car and the lights were so yellow you couldnt even see in them..

Sand the headlights with 1000grit and work your way to 3k grit. Then spray thr lights with a UV protectant clear coat and sand again to 3k then use buffing compound.

The lights looks amazing.

 

Use the 3M headlight restoration kit and get an Xpel kit.
