More than just a temporary coating needing constant reapplication, Diamon Fusion molecularly fuses with glass to form a permanent hydrophobic barrier. It creates a new chemical bond that greatly enhances visibility in bad weather and strengthens weight load up to ten times. As a result, water instantly beads up and rolls away, and small debris simply ricochets off. -The Advantages Of Diamon Fusion Are Crystal Clear...
