Restoring FADED and YELLOWING Headlights on an Audi A3 

3M probably the best restoration kit available for home restoration there is, Couple things worth mentioning are firstly p220 is far to abrasive for polycarbonate headlights, At max no lower than p320, In your case p500 is more than enough! That's why 3m include extra disk of this size as the initial sanding removes the worst of the oxidation and old clearcoat + Grime, I also stop and start to dust is unnecessary, A compressed air duster for computer key boards works well to remove dust, When using the p3000 trizact disk one application of water to lens is all that's needed!! When the water becomes cloudy and milky evenly across the lens stop, Use any glass cleaner spray to remove the residue wipe and dry before using the polishing!! And lastly I didn't like the sound of that ceramic coating?? I only use products that are certified such as Maguires clearcoat with added UV protection for car headlights!! Apart from that you did a brilliant job well done👍Its nice to know young men using the best method for restoring headlights ever!!🤔🧐😃

Looks good. I use meguiars keep clear headlight spay coating. I’ve had it on my headlights for about 6 months and still looks great. A can costs about $7 and I havent even used half the can after 3 cars headlights restored.

So how long did the ceramic Cody last? It's still an effect.

I wonder what people do to get them that bad? I have a 2008/09 and my headlighs are as new, even after 15 years

Headlight looks great after sanding and polishing. However, a spray can of $23 spray can of 2K clear topcoat will protect the plastic headlight lens from fogging up again for many years.
