What's the best headlight cover to keep them from becoming fogged and yellow? 3M XPEL sounds good and I hear of people buying a section of 3M film and cutting it to fit. I've also heard of people using Plasti Dip clear spray as an easier alternative to the film. Reading the FAQ at invisiblemask.com, the 8mil paint protection film may be best for headlights and can be purchased by the foot instead of being precut for headlights.


Has anyone found what works well and a good source to purchase this?

 

Yup, ppf is a great choice for headlights.

You can also use a headlight coating like Optimum Opti-Lens to help prevent discoloration.

 

Will the PPF alone prevent yellowing? Doesn't the film itself yellow after a little while? Every white car you see that had PPF done after a couple of years is always a little more yellow regardless if it was coated afterwards or if it's a good quality or crappy quality film.

In for real answers.

 

PPF should provide adequate protection.

When headlights start to fade, it is because the surface is oxidizing. You can correct this by removing the oxidation with machine polishing (and sanding when needed), but without adding protection, the bare plastic will oxidize again in a short time. Since good PPF (like xpel ultimate) resists oxidation, yellowing, etc. it should help to keep the headlights looking good for longer periods of time.

Would I consider it 'permanent fix'? No... I imagine at some point it will need to be replaced, however Xpel offers a 10 yr warranty against yellowing, cracking, etc.

I'm certainly no expert with PPF, so someone else can certainly chime in. I may be off base.

 

Well I definitely would no count on that....
