Gyeon Q² One EVO

by Gyeon

We Say

Gyeon Q² One EVO is an easy to use entry level quartz coating aimed at detailing enthusiasts with access to a dry indoor workspace. Developed in South Korea, Gyeon Q² One EVO lays down a film of siloxane polymers that condense rapidly to form a fully crystallized SiO2 coating that bonds to painted surfaces at the molecular level. Thanks to its pure formulation, full curing successfully occurs at low temperatures, which makes it well suited to use in unheated domestic garages. Like the other SiO2-based coatings in the Gyeon range, it delivers superb looks characterised by strong colour jetting and excellent levels of gloss. In fact, its colour enhancing effect is easily on par with many good quality carnauba waxes, making it the perfect coating for warmer coloured paint finishes (e.g. solid reds). In addition to fantastic looks, Gyeon Q² One EVO offers a number of other benefits...

Firstly, because it contains no alcohol, it doesn't flash off rapidly upon contact, which makes it very easy to apply. Moreover, because it is a very thick coating, only a single layer needs to be applied. Secondly, because it fully crystallizes as it cures, Gyeon Q² One EVO produces a substantially harder and more durable coating than many rival products. We've tested this by subjecting it 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, and; (iii) clayed with a mild clay bar. The net effect of this treatment was only a slight reduction in beading strength compared to the day it was first applied. Given that it's essentially a simplified version of the now retired Gyeon Q² Prime formula, we fully expect its durability to extend to around the twelve month mark.

Gyeon Q² One EVO is a user-friendly quartz coating that simultaneously protects and enhances the appearance of automotive paint. Developed in South Korea, Gyeon Q² One EVO uses the latest in low volatile content silicon (Si) technology to lay down a film of pure siloxane polymers that condense rapidly to form a fully crystallized SiO2 coating that bonds to painted surfaces at the molecular level. Unlike many coatings, Gyeon Q² One contains no alcohol and therefore doesn't flash off rapidly, which makes the application process much easier. Furthermore, because it is designed to be wiped on and then wiped off immediately, it is no harder to apply than a natural carnauba wax. Nevertheless, despite how easy it is to use, Gyeon Q² One EVO features significantly more SiO2 than is usually the case for entry level coatings, which gives it class leading durability at a very affordable price point.

As a result of being coated with a smooth, dense layer of crystallized SiO2, treated surfaces become extremely hydrophobic (water-hating), which causes rainfall and rinse water to bead up and roll off very quickly. This extreme beading not only looks good, but also tends to pick up and carry away fresh contaminants, which makes routine washing easier and much safer. In addition to these benefits, Gyeon Q² One EVO also provides high levels of protection against bird droppings, bug splatter, road salt and harmful UV radiation for up to twelve months, even on daily drivers (it is virtually impervious to cleaning chemicals and pressure washing). Gyeon Q² One is currently supplied as a pre-packed kit containing either a 30 ml or 50 ml bottle of Gyeon Q² One, a 100 ml bottle of Gyeon Q²M Cure, a Gyeon Q²M Applicator, stickers and an instruction booklet.

How To Use

You should apply Gyeon Q² One EVO 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, wrap one of the supplied Gyeon Q²M Applicator Suedes around the supplied Gyeon Q²M Applicator Block and lightly wet one end of it with Gyeon Q² One EVO using the supplied dropping pipette. Then spread the coating quickly over the first panel, using light pressure and overlapping strokes. After 20-30 seconds, and without adding any more product, rub the Gyeon Q²M Applicator Suede over the panel in tight circles, using moderate speed and pressure. This step is critical, as it levels the coating and makes it easy to remove. You must then buff off the remaining 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 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 you must then leave the car in a dry place out of direct sunlight for a minimum of 24 hours to allow the SiO2 coating 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 protective topcoat of Gyeon Q²M 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 Gyeon Q² One EVO, because it 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.
