Gyeon Q² Mohs EVO Light

by Gyeon

We Say

The Light versions of Gyeons coatings are no different to their regular coatings, the only difference is they contain the coatings only. These are great for those that don't require the extra bits included. In the case of Q2 Mohs EVO Light, it doesn't contain the Q2M Cure. If you require the full kit, it can be found here: Gyeon Q2 Mohs EVO

Gyeon Q² Mohs EVO Light is a state of the art quartz coating that simultaneously protects and enhances the appearance of automotive paint. Developed in Japan, Gyeon Q² Mohs EVO Light 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 EVO Light 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 EVO Light 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 pencil hardness 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 EVO Light 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 EVO Light is currently supplied as a pre-packed kit containing either a 30 ml or 50 ml bottle of Gyeon Q² Mohs EVO Light, a Gyeon Q²M Applicator, Stickers, and an instruction booklet.

How To Use

You should apply Gyeon Q² 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 Q²M Prep to ensure that they are spotlessly clean. Next, using the supplied dropping pipette, lightly wet a Gyeon Q²M Applicator Suedes with Gyeon Q² Mohs, wrap it around a Gyeon Q²M 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 1-2 minutes you must then buff off the (still wet) residue as quickly as possible, i.e. before it 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 dry place out of direct sunlight for a minimum of 24 hours to allow the layers to harden (if you wish, you can accelerate this process by heating the treated panels to 60°C 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 final topcoat of Gyeon Q²M Cure (you should also avoid washing the car with any kind of detergent for 7 days following application). Please note that you must discard all used applicators and towels after you've applied each coat of Gyeon Q² Mohs because it becomes extremely hard 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 wash out the pipette with hot running water. Failure to follow these steps will most likely result in any leftover product setting solid in the bottle and the dropping pipette, rendering them unusable in the future.
