Z-GLASS is a coating specifically designed for glass. It has excellent durability and does not affect the motion of wipers. Super hydrophobic effect of the coating allows water to simply bead up and flow off the glass while you are driving. Z-GLASS lasts for up to 12 month in automotive use and up to 5 years in glass building/construction application.
Unprotected glass can be a hazard during rain as water can cover the windows decreasing visibility and becoming a safety hazard. Having Z-GLASS on all windows will increase the visibility by repelling water and allowing it to bead up and flow right off the glass. It will also keep the glass cleaner for a longer time since dirt and grime will no longer stick to it.
