3 years of Gyeon Q2 Mohs quartz coating

When we bought our GTO the car was treated the car with quartz coating. The coating is now applied on the car and the rims 3 years ago. Time to share my opinion. It’s expensive, but proven to be worth every Euro. It has been 3 years just washing the car after every drive. Polishing or detailing is no longer required. And when you use the proper materials for washing swirls stay away for ever. Big thumps up for this product. 3 years ago these products where relatively new. Current status is that several suppliers offer quartz coating products. A worthwhile investment if you want to save a lot of time. The Donkervoort factory now offers this treatment as a service on new cars.


Gyeon Q2 Mohs is the ultimate state of the art quartz coating offering significant levels of gloss, protection & durability. Manufactured using the very latest advances in low solvent SiO2 technology make Gyeon Q2 Mohs much easier to apply than comparitive products but also offer genuine laboritory tested hardness and durability to the surface.

Gyeon Q2 Mohs is the hardest automotive paint coating available to a wide range of users. Given the average automotive paint hardness, which lies within the range of 3-4H according to the Mohs scale, Gyeon Q2 Mohs adds a further 3H, which makes the paint extremely resistant to scratches. The extraordinary hardness of the coating preserves the effects achieved during the paint correction and is synonymous with a much slower paint degradation during maintenance.

As opposed to the majority of coatings present on the market, Gyeon Q2 Mohs demontrates the lowest shrinkability parameters. Whereas most coatings shrink from 0.2 up to 0.03 microns, the shrinkability of Q Mohs does not exceed the level of 5%, while its thickness – 0.2 microns as registered just after application, drops to 0.19 when fully dried. Traditional protective products such as wax or polymers do not display any measurable thickness whatsover.

Durability is one of most salient merits of the product. It is able to maintain 80% of its original hydrophobic properties and to last on the paint throughout a period of at least 12 months, thus being a guarantor of optimum car protection against environmental factors and exploitation conditions. If juxtaposed with waxes, even the top-performing ones, it lasts three times longer.

The self-cleaning ability ensures the impeccable appearance of a vehicle between consecutive washes, as it drains most pollutants in a very simple way. Hence, the maintenance of a car becomes completely trouble-free and most contaminants may be removed by pressure washing. Q2 MOHS is easy to apply also on dark colored paints. Each added layer will improve durability and scratch resistance. Note: The product should only be applied on paint in very good condition, new or just after a paint correction.
