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.

Do not waste your money
Style: Headlight Restore & Repel Kit
The spray bottle sprayed one time, that's one pump. This is ridiculous.
