Q² Mohs EVO uses fluoro-modified polysilazanes for the first time in the car care industry. Why is that so important? Modifying polysiloxanes at the precursory stages brings enormous benefits on all levels: durability, chemical resistance and ease of use. It is amazingly easy to apply and wipe off, yet highly chemical resistant. Slick and smooth, yet very durable. Gloss and extreme hydrophobia are just value-added.
