Krystal Diamond is a state-of-the-art paste wax that is formulated using SiO2 (silicon dioxide) fused with all-natural carnauba wax to provide unmatched levels of gloss and longevity. Krystal Diamond SiO2 Ceramic Car Wax imparts depth and warmth to darker colors; lighter colors, like white and silver, will appear glassy with vibrant, crisp reflections.
