I use Turtle Wax Express Shine after every wash, and IMO, the paint still looks brand new. Use what you like.

If your paint needs some extra TLC, try some Mothers Clay Bar. Some work involved, but does a great job. You have to get the paint looking good before you can depend on detail sprays. Detail sprays will help maintain, but not bring back.

To answer your question, I have not heard of it or used it.
