Every year I think about ordering some Aquapel so I don't have to apply Rain-X weekly during the spring, but ultimately decide against it. Why? Because I've read a lot of reviews that claim it's just not quite as effective as Rain-X, despite lasting a lot longer per application. In particular, I've heard that it results in smaller beads, and that these beads don't start blowing off the windshield until you reach significantly higher speeds than is the case with Rain-X.
Can anyone with firsthand experience using both verify whether or not this is true?
