I bought N-914 Rinseless Wash & Wax after seeing a number of videos on YouTube, and thought to myself that it could not possibly be as good and easy to use as they said. But as the price is quite reasonable, I bought it to see for myself, and I was wrong! It is easy to use - cleans the car quickly without having to rinse, but the real surprise is the long lasting shine. Remember, a little goes a long way so be sure to dilute it properly. I used 4 capfuls for 2 gallons of water and that was more than enough to put a smooth silky surface on my car. That was 4 days ago, and my car still looks like I spent 2 hours washing, waxing and polishing. I also have a separate spray bottle with a more concentrated mixture that works as a detail spray. In short, this is a great product that does what it says. Just follow the advice in the videos.
