I have the nanosealing used as protection for my recycled acrylic glass headlights. The set are in addition to the cleaning liquid and the sealing when even a sponge and a small fleece for applying. The application is a matter of a few minutes and after the first few rides in the rain, the headlights are also nice and clean and clear. How long the protective layer really holds and how it is more resistant to environmental influences, will turn out in the coming winter in mud, road salt and Split.
Update October 2013: The headlights were still clear after about a year, after preparation and sealing. I have now just again polished and renewed the sealing. Absolute buy recommendation.
