    Sprayer broke
    Style: Headlight Restore & Repel Kit

    The stuff works.
    Style: Headlight Restore & Repel Kit
    This stuff works great, very easy to use and reasonably priced. It took headlights from that yellow haze where you can’t see the bulb inside you know what I mean to looking like a new light I couldn’t believe it worked that well with no sanding at all. just use the wipe to wipe the lens for a minute or two and it’ll clean all the oxidation off. Let it dry for a few minutes and then spray the ceramic coating on it and you’re done make sure and let the coating dry for a few hours before you touch it.

    Don't get this for the protective spray.
    Style: Headlight Restore & Repel Kit
    The protectant spray is terrible. It is a pain to put on and streaks and runs. The instructions don't really help get decent results.
