Found Drivers side headlight defect

Forum members. See attached picture of my front drivers side headlight which i thought was from PPF. After my installer removed it he took the attached picture. Def looks like some enamel type of substance on the outside. Iím thinking could this be factory defect? Welcome comments.

That isn’t a headlight defect, your installer shouldn’t have removed the PPF from them.

Porsche headlights are the same, if you PPF them, then remove it, it damages the polycarbonate and takes a layer of the protective coating on the headlight off with it.

I'm sure you're right, but it makes me wonder why anyone would ever PPF headlights then?

Mine are PPF'd, hence my question.

Mine are too, you really only get one shot at a lot of headlights so it’s all about who you use. My guy does all my cars bumper to bumper and is about as OCD as they come. Exactly you’d want for a PPF guy. Even he didn’t want to do the headlights on my GT2RS given their convex shape and that’s when he explained to me the risk.

You could probably take some 1000, 1500 then 2000 grit sandpaper and wet sand the headlights, plastic polish then PPF and you’d be good. I’ve done it before, but on much lower risk headlights so a professional may be a better call. If McLaren replaces them, that’d be great but I’d be curious to see how that warranty claim goes.

Thx for the reply. Just to clarify the defect was already visible with the ppf and I asked him to removed it to see if it were air pockets from the ppf which we then found out it wasnít the case...

I ppf'd my GT2RS lights since track usage. It is all about how the film gets removed. Great installers know to use a heat gun and very carefully remove the film. Done it on prior Porsches as well.

This looks like something dripped or splattered onto the headlight and was left on. I remember years ago a friend's dog, a Great Dane (Smoochie), that would shake his head and saliva would fly everywhere. If it hit a painted surface or car window it was almost impossible to remove especially if it was baked in the sun.

Also, it is my understanding that the ppf adhesive layers have been vastly improved. One of the reasons installers used to like Suntech because it could be more easily lifted up during install. The new Xpel ultimate plus supposedly now has a more forgiving adhesive layer.

Yup I was told my my installer to not put any PPF on the Porsche headlights.
