Today we are reviewing a big boy product! GYEON quartz MOHS was suggested to us and we were determined to have it tested out to see how it would compare to other Ceramic Coatings in the detailing industry.
Just to clarify - we are not sponsored by Gyeon, or any other manufacturer of Paint Protection products, and we will test and review the product as it is in real-world conditions. We will follow the manufacturer's instructions during the application process and we will prepare the surface to ensure the best finish and best adhesion possible. We are leaving an affiliate link to all our review products but in case the product turns out to be of low quality or not as all as advertised we leave a warning to all our readers and the quality of the product will always be reflected in the grade we assign to it at the end of every review. So if you do not want to sit through all of this text, you can scroll down to the Average Grade and read our Final Thoughts to get a general idea of what the product is all about.

Gyeon is perhaps not as well known in the automotive detailing industry as some other brands but it came to us recommended and is being held in high regard. We will put it to a test and see what it's all about!
We were promised that this product would perform amazingly compared to other products. But naturally, we cannot review products just like that without having them tested and seeing the results with our own eyes beforehand.
So let us see what this product offers:
the hardest coating widely available
extremely high gloss
at least 18 months
2 layers requirement
'The hardest coating widely available' would be a tough one to beat. All the other claims sound very good except the duration - 18 months.
That one seems low. But if it is 18 months of real-world usage, then that would be quality instead of a downside. We will test all of them.
Ok, now, the first thing to do is - prepare the car's surface so it can be properly coated with Paint Protection. To learn how to prepare the surface of your car for Ceramic Coating, you can click here.
Now that the car's paintwork and other areas are ready we will read the product instructions to see what we need to do next.

How to apply GYEON quartz MOHS properly?
With the product comes an applicator block and a microfiber suede application towel that we are supposed to wrap around the applicator block. After that, you apply several drops to the length of the application towel and we are supposed to apply a thick layer in a criss-cross pattern to ensure full coverage and wipe off immediately after application. Be sure to use another clean and dry microfiber towel to buff off the solution to a glossy shine.
After the 1st layer has been applied and buffed off, you are to wait 1 hour before applying the second layer using the same technique. So what you can do is to check the time when you start applying the 1st layer onto the whole vehicle and then start applying the 2nd layer starting from the same spot as the 1st layer when the 1-hour mark is up.
If you apply that thick layer, GYEON quartz MOHS can be a little bit tough to buff off at times. Because of that, we presume it is very important to buff the product as soon as possible and not work in extensive areas to avoid using too much elbow grease.
Ok, the product has been curing in the garage for more than 24 hours and it is ready to be tested. We will leave the car in direct sunlight for the next 2 weeks and will be using the vehicle during that time by driving it daily in town and a few miles doing some light offroading to accumulate a fair bit of dirt and dust. We will also wash the car 10 times during that period using a standard car shampoo that is not pH neutral but instead a common car shampoo that anyone would most likely use when washing their vehicle in a DIY fashion.
How did GYEON quartz MOHS perform?
After the first day, the vehicle wasn't that dirty at all. And we think it might be due to the slick surface it has created once the coating has fully cured. Because in other tests, even in dry conditions, dust and or dirt seemed to stick a little bit more to the paint. That was already a good sign.
We proceeded to wash the car with regular car shampoo using a microfiber wash glove and a bucket with a grit protector. We have rinsed the shampoo off the vehicle using a pressure washer. The water sheeted off more than it was forming water beads. That is again, very good news and would be easily explained by the slickness of the surface. It left an almost completely dry surface with a couple of beads of water standing here and there. We have also tried giving the paint a few scratches using the abrasive part on a dishwashing sponge.
For the scratching experiment, we have chosen the right-hand side of the hood panel. We also focused on using circular motions when cleaning and applying light pressure since hard pressure would surely leave deeper swirl marks. There were no visible swirl marks at this point.
We continued repeating the same process for the remainder of the 2 week testing period and we saw some drop in performance even after a couple of washes, but the performance didn't decrease but slowed down the sheeting process from a few seconds to about 8-10 seconds per panel.
The end result was still the same, we just had to wait longer. At the end of the 2 weeks, we started to see some swirl marks as to be expected after so much scrubbing. But they were minor and visible only under direct light and at a slight angle even.
Our verdict on this product:
product life time when applied: C
resistance to elements: B
resistance to damage: B
resistance to chemicals: B
application difficulty: D
hydrophobic properties: A
gloss / shine: A
Average grade: B
Cost: 45.98$ / 1 fl oz
2.59$ / 1 ml
Final thoughts on GYEON quartz MOHS Ceramic Coating?
GYEON quartz MOHS Ceramic Coating is one of the most expensive products we have bought so far. But was it worth the price? Well, actually yes. The reason, we feel, was that most Ceramic Coatings have amazing hydrophobic properties, this one included. Still, hydrophobic surfaces tend to leave water beads that aren't heavy enough for gravity to do its thing. And if there is no wind and you don't wipe the car or drive it, it might result in water spots.
Well GYEON quartz MOHS Ceramic Coating has excellent water sheeting properties that are achieved due to its very slick surface once the Ceramic Coating has hardened. We have noticed a difference in how dirty the car was before each wash also for the same reasons as above. That alone keeps the car cleaner and made it even easier to clean.
Standard Ceramic Coatings are harder to apply than Spray-On versions, but this product took that even a step further by requiring two layers making the application process among the most tedious ones we have worked with. Also, its duration isn't advertised as long as you would get from other Ceramic Coatings but while it did show a drop in performance during and after the testing it still performed really well. The product visibly deepened the car's paint enhancing it and making the car stand out a bit more than it normally would.
Considering the price of the product and the lifetime you get with it, we would place it among the most expensive, if not THE most expensive Ceramic Coatings, that we have worked with. But if you have money and you are looking for guaranteed results and the qualities it showed are the ones you are looking for, we say go for it! You will pay more, but at least you will know what you got for your money.
