I have been unable to contact KozMez (Crystal Guard) by phone and email messages are returned. Anyone know if they still are in business? Actually what I wanted to know from them is why the great water repellency that I had after the 2nd application in 4 months virtually disappeared after a 2 hour hi-speed drive in a bad rain storm. Before rinse water would bead like crazy but after washing the car after the drive in the rain the water just sheets off especially on the vertical surfaces. I used the same Blue Coral wash as I always have.
