This stuff works! It also solved an issue where my wiper motor is a bit weak on an old MB. Therefore, it barely would move across the windshield. I thought I was going to have to replace the motor and gear assembly, but simply putting this on the windshield makes such a difference in slipperiness/smoothness, that I no longer have an issue with the wiper stroking the windshield properly.
6 months later, I had to reapply it....because I had to have the windshield replaced ;)This stuff beats RainX HANDS DOWN!
nice product last about 6 months through out the summer in to winter- fair price
Fantastic water repellant. Works really well, and lasts a long time. A bit tricky to put on; just make sure you read the directions carefully and maybe wear some older clothes when you're applying it. Well worth the time to treat your windows!
worked as described. 2 out of the 6 arrived busted open.
