wow, i have used a lot of products for my cloudy headlight lens. this was the easiest and the best so far. on a dry clean headlight, open the foil envelope and get the wipe out, wipe the cloudy headlight and it really gets the job done, a yellow stain builds up on the wipe. one wipe for each headlight. wipe dry with microfiber, then spray the sealant and let it sit, just wipe any excess run off on the car body. poof, done! looks good. says it can last up to 18 months. not sure about that, but i will take what i have now. go nu finish, another solid product.

Sprayer broke

Style: Headlight Restore & Repel Kit

Spray bottle broke half way through the 2nd light. Made do with dumping the liquid on a paper towel and wiping it on, but can already see spots on it

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.
