I have a Baggershield. Info came with my shield said not to use any type water repellant on their shield. Just water and micro-fiber cloths for washing and drying. I suppose each manufacturer has their own rules for cleaning. I stopped at a vendor booth in Sturgis, that was offering a product called Z-Clear. They claim it will fill micro scratches in cycle windshields, and restore their clairity, and will make water repell off them. I got a sample for my sunglasses, and seems to work on them. Haven't tried it on my bike shield, as it's not scratched. Their info is at Z-CLEAR.com.
