After I purchased the product, the slices were so treated (delivery via Amazon as always top). As described on the package on the discs applied with a cloth and after a drying time polished away (about 5 minutes) with a fresh cloth and polished and polished and polished ... takes a bit until all streaks away ... Subjects covered were the front and side windows and mirrors ... then came at a forthcoming rides the rain ... - Best on the highway from approximately 70 / 80km / h. On the discs (front and side windows, Spigel) the drops were flying away. They even did not need wipers. - In the city (about 55km / h) not so great - for the windscreen - top side windows and mirrors, everything flies away and runs great from. On the windscreen wiper had to be active and then ... streaks without end ... this I have now after two weeks still.
Conclusion: Awesome for side windows and door mirrors and recommended. Since there is soon a further treatment. Only good if never the wiper is used on the windshield. It lubricates otherwise formidable.
Packaging was good - no leakage and product was full.
