    Windshield repair kit on headlamps -any problems?

    Before I put clear bra material over the headlamps, I'd like to fill/repair two tiny pits/cracks that I've accumulated on my headlamps. I'm thinking of using the same DIY windshield repair kit that works well on glass. Correct me if I'm wrong, but I do believe the headlamp covers are made of plastic? If yes, then does anybody see a problem with potential corrosion by the resin that is used to fill a windshield crack? Just being cautious. Thanks much.

     Well, I'm answering my own question; no problem with resin and headlamp plastic compatibility. However, the fix is not seamless (perhaps due to the layered construction of windshield glass??). While the injected resin decreases conspicuity of the tiny crack, it doesn't eliminate it as it does on a glass windshield. All in all, no big deal.

    hmmm, guesing that the refractional index of the resin is tailored to be equal to that of glass, thuss being seemless when applied to a windshield.
    The headlight "glass" is plastic and will have a different refractional index -> not seemless.

    Did you see any chemical reaction of the plastic to the resin, or did it just fill the pits without any drama?

    ...I was thinking the same, Joost.

    No major drama with regard to chemical reaction (I used the "fix-a-windshield" version, btw). However, I hesitate to "scrape" off the excess with the supplied razor blade (done at 90 degrees to the surface), since plastic is a lot softer than glass. I think I'll just buff smooth the area (mainly for good luck, since it's already very hard to notice anyway) with scratch remover instead.

    You're welcome Lars997! Just thought I'd add to the collective knowledge base. Smiley
