Gyeon Q² Mohs

Gyeon Q² Mohs is a state of the art quartz coating that showcases the latest advances in low volatile silicon (Si) technology. If, like us, you always question relative performance in the world of car care, then you're probably wondering how Gyeon Q² Mohs differs to rival products, and what it offers that they don't? The answers to these questions stem back to its unique alcohol-free formula, which lays down a hybrid film of organic-silica that increases in molecular weight as it cures, forming a pore-free organic-silica nano-composite. None of the other SiO2-based coatings we stock work in the same way; they lay down glass-like coatings that form strong molecular bonds and, in some cases, fully crystallized lattices, but none are as structurally dense (and thus as resistant to physical and chemical attack) as Gyeon Q² Mohs. This is supported by the fact that each layer of Gyeon Q² Mohs shrinks by less than 5% as it cures, whereas the average figure for other SiO2-based coatings is 30%.

Now that we have confirmed how Gyeon Q² Mohs differs to rival products, we can look at the benefits it offers. Firstly, because it contains no alcohol, it doesn't flash off rapidly upon contact, which makes it easier to apply. Secondly, because it forms a pore-free composite as it cures, it produces a substantially harder and more durable coating than rival products. We've tested this by subjecting Gyeon Q² Mohs to a brutal decontamination test, in which selected panels were: (i) treated with a spirit-based tar remover; (ii) treated with a strong acid-based fallout remover; (iii) clayed with a mild clay bar, and; (iv) treated with neat isopropyl alcohol. The net effect of this treatment was negligible; the panels were left beading just as strongly as the day the Gyeon Q² Mohs was first applied. Furthermore, in a long-term test on a daily driver, we observed clear signs of functioning protection through to the two year mark, which places Gyeon Q² Mohs in a league of its own in terms of durability.
Gyeon Q² Mohs is a state of the art quartz coating that simultaneously protects and enhances the appearance of automotive paint. Developed in Japan, Gyeon Q² Mohs uses the latest in low volatile content silicon (Si) technology to lay down a hybrid film of perhydropolysilazane (PHPS), hydroxyl-rich organic copolymers and poly(methyl methacrylate) (PMMA) that condenses rapidly to form an amorphous organic-silica nano-composite that chemically bonds to painted surfaces at the molecular level. Unlike rival products, Gyeon Q² Mohs actually gains molecular weight as it cures (as skeletal Si-N bonds are replaced with Si-O bonds), which improves its structural integrity and restricts its shrinkage to 5% during the curing process (the average figure for SiO2 coatings is 30%). As a result, each coat of Gyeon Q² Mohs imparts a measurable 0.2 micron increase in total paint thickness, and significantly improves the scratch resistance of the underlying finish; on average, each coat adds two grades of hardness (2H) on the Mohs scale.

As a result of being coated with an ultra-smooth, extremely dense layer of this organic-silica nano-composite, treated surfaces become hydrophobic (water-hating), which causes rainfall and rinse water to bead up and roll off very quickly. This beading action not only looks good, but also tends to pick up and carry away fresh contaminants, which, combined with the naturally high scratch resistance of the coating, makes routine washing easier and much safer. In addition to this strong self-cleaning effect, Gyeon Q² Mohs also provides excellent protection against bird droppings, bug splatter, road salt and harmful UV radiation for up to two years at a time, even on daily drivers (it is impervious to cleaning chemicals and pressure washing, and once fully cured can only be removed by machine polishing). Gyeon Q² Mohs is currently supplied as a pre-packed kit containing either a 30 ml, 50 ml or 100 ml bottle of Gyeon Q² Mohs, a 100 ml bottle of Gyeon Q²M Cure, a Gyeon Q²M Applicator Block, four Gyeon Q²M Applicator Suedes, a 3M disposable respirator and an instruction booklet.
You should apply Gyeon Q Mohs in a dry place out of direct sunlight. In all cases, prepare the surfaces you are going to treat in the normal way (wash > decontaminate > polish), and then do a wipe down with Gyeon QM Prep to ensure that they are spotlessly clean. Next, using the supplied dropping pipette, lightly wet one of the supplied Gyeon QM Applicator Suedes with Gyeon Q Mohs, wrap it around the supplied Gyeon QM Applicator Block and begin wiping it evenly on to the first panel, using light pressure and overlapping strokes. You should aim to treat no more than a single panel at a time, because after an initial volatilization period of 3-5 minutes you must then buff off the (still wet) residue as quickly as possible, i.e. before it dries out and begins to harden. Buffing off is best accomplished with a PB Super Buffing Towel using moderate speed and pressure in order to fully remove the residue and reveal an intense streak-free shine. Using a bright light, check the panel carefully for any smears and remove them before moving on; failure to remove smears fully can result in them hardening to the point of being impossible to remove without machine polishing, so make sure you are thorough!

After all panels are treated, wait for a minimum of an hour and then apply a second coat. The car must then be left in a warm, dry place out of direct sunlight for a minimum of 24 hours to allow the organic-silica nano-composite to harden (if you wish, you can accelerate this process by heating the treated panels to 60C for 10 minutes using an infra-red heat lamp). Finally, to reduce the risk of water spots forming while it continues to cure (full curing takes around 14 days to achieve), you should apply a protective topcoat of Gyeon QM Cure (you should also avoid washing the car with any kind of detergent for the first 7 days). Please note that you must discard all used applicators and towels after you've applied each coat, because Gyeon Q Mohs hardens massively as it cures, forming a residue that has the potential to inflict severe marring or worse if applicators and towels are re-used. Furthermore, after each use you must also replace the dropping pipette with the air-tight cap, and then wash out the pipette with hot water. Failure to follow these steps will result in any leftover product setting solid in the bottle and the pipette, rendering them unusable in the future.
