I use this for almost 20 years, it protects the body paint, UV headlights and rims and brake pads deposits. Greatly facilitates cleaning, dirt, flies no longer sticks to the body, even the tar adheres less, like alloy wheels or a simple sponge is enough for what again become like new. This is a resin which is deposited using a cotton on the body, headlights and wheels and makes as a "varnish" drying. Then, after about half an hour, we remove with a cotton cloth the excess of resin and the car becomes particularly smooth and shiny, you will see the water flowing down the paint. Applies only on new or gloss paint is perfectly clean for not locking the dirt between the resin and paint. But be careful to avoid deposit on the rubber seals, which in this case remains white after drying, ditto on some black plastics Mat and grainy.
