Gyeon Q2 Mohs EVO vs Q2 CanCoat EVO
Same brand, same documentation habits, three times the durability claim. The interesting part is that Gyeon publishes consumption for both, so the cost per car is calculable.

The ladder, in Gyeon's own numbers
| Q2 CanCoat EVO | Q2 Mohs EVO | |
|---|---|---|
| Size | 200ml | 30ml / 50ml / 100ml |
| Claimed durability | Up to 12 months / 12,000km | Up to 36 months for 1 layer, 48 for 2 |
| Published consumption | 10-15ml per car | 15-25ml per car |
| Applications per bottle | About 13 to 20 from 200ml | About 2 to 3 from 50ml |
| Water-free period | 12 hours | 12 hours, out of direct sun |
| pH tolerance | 2 to 11 | Not published |
| Application | Sprayed and wiped | Applied and leveled |
| In the box | Coating, 3 spray heads, microfiber | Coating, applicator, Q2M Cure 100ml, manual |
The arithmetic Gyeon lets you do
This is the rare comparison where both products publish consumption, so the cost question is answerable rather than a matter of opinion. A 200ml bottle of CanCoat at 10 to 15ml per car is roughly thirteen to twenty applications. A 50ml bottle of Mohs at 15 to 25ml per car is two to three.
Put those against the durability claims and something useful falls out. CanCoat is a product you will apply annually and have most of the bottle left over three years later. Mohs is a product you will apply once and have a partial bottle you should probably use on a second vehicle rather than store for three years. Gyeon does not publish US list prices, so the final cost comparison has to be done at the retailer — but the volumes are the part that decides it, and those are published.
The application gap is the real decision
CanCoat comes with three spray heads because it is meant to be sprayed onto an applicator or a panel and wiped. Mohs comes with a coating applicator and a bottle of Q²M Cure because it is meant to be laid down in a controlled film and leveled before it flashes. Those are different skills, and the second one is the one people get wrong.
A high spot in a leveled coating is not a cosmetic complaint. It is a raised patch of cured silica that will not wipe off and has to be machine-polished away, taking the surrounding coating with it. On a first attempt, in a garage with bad lighting, that is a realistic outcome. This is why the recommendation at the top of this page is the shorter-lived product: the failure mode is much cheaper.
What the extra 24 months actually buys
Two years of not re-coating, and a harder film. Whether that is worth the application risk depends almost entirely on how long you are keeping the car. On a vehicle you will own for five years, Mohs is obviously correct. On a lease with two years to run, CanCoat covers the whole term and costs less in both money and stress.
There is also a middle path Gyeon does not advertise: CanCoat now, Mohs at the next correction. Coating a car teaches you more about coating a car than any guide does, and doing the low-stakes version first is a genuinely sensible way to arrive at the high-stakes one. The worth-it page works through the money side.
Every pick, with the working
Each entry lists the specifications the maker publishes, the axis scores those specifications produce, and what you give up. Rows that read “Not published” are not omissions on our side: they are figures the maker will not commit to in writing, and they cost the product points on the transparency axis.
Our pickThe longest durability claim anyone here puts in writing
Gyeon Q² Mohs EVO
Gyeon
Gyeon claims 36 months for one layer and 48 for two, which is the longest published figure in this ledger, and the page states a consumption rate of 15 to 25ml per car so you can work out how many cars a bottle covers before you buy it. What Gyeon does not publish is a solids or SiO2 percentage, so the number that would let you compare its chemistry to CarPro's is missing.
- Sizes
- 30ml / 50ml / 100ml
- Claimed durability
- Up to 36 months (1 layer), 48 months (2 layers)
- Published consumption
- 15-25ml per car
- Water-free period
- 12 hours, out of direct sun
- In the box
- Coating, applicator, Q²M Cure 100ml, manual
- SiO2 content
- Not published
- Application temperature range
- Not published
- List price
- Not published
What it does well
- 36 months claimed for a single layer, 48 for two, published on Gyeon's own product page
- Consumption published as 15-25ml per car, which is the figure that tells you what a 50ml bottle actually covers
- Ships with Q²M Cure, an applicator and a maintenance booklet rather than a bare bottle
- Three sizes, so a single-car job does not require the professional bottle
Who it is not for
- No SiO2 or solids percentage published anywhere on the product page
- No application temperature range published, which matters for a garage job in winter
- Gyeon does not publish a US list price, so the cost per car cannot be calculated from their own figures
How this score was calculated
- Protection claim6.0/10, weight 20%
- Gyeon claims 36 months, scored against the 60-month ceiling this category tops out at. That is the manufacturer's claim reported here, not a durability figure anyone measured for us.
- Capabilitydropped
- Gyeon does not publish a figure for published sio2 content on this product, so the axis is dropped and the remaining weights are re-normalized.
- Cost per ouncedropped
- Either the list price or the container size is unpublished, so the division cannot be done and the axis is dropped.
- Price against the ceilingdropped
- The maker publishes no list price, so there is nothing to score here and the axis is dropped.
- Written commitmentdropped
- Gyeon publishes no warranty term on this product's own page, so the axis is dropped. On a tool that is worth noticing, and it costs the product points on transparency instead.
- Spec transparency6.3/10, weight 18%
- 5 of the 8 specifications we went looking for are published by Gyeon. Every blank row below is something the maker will not put in writing, and it costs the product points here.

2A first real coating that forgives a bad panel
Gyeon Q² CanCoat EVO
Gyeon
A 200ml spray-applied coating claiming 12 months, with a published consumption of 10 to 15ml per car and a stated pH tolerance of 2 to 11. It is the coating to buy when the honest answer is that you are not ready to level a proper one, and the consumption figure means a bottle is roughly a dozen applications.
- Size
- 200ml
- Claimed durability
- Up to 12 months / 12,000km
- Published consumption
- 10-15ml per car
- Water-free period
- 12 hours
- pH tolerance
- 2-11
- In the box
- Coating, 3 spray heads, microfiber
- SiO2 content
- Not published
- List price
- Not published
What it does well
- 12 months claimed for a product you spray and wipe rather than level
- 10-15ml per car published, which makes a 200ml bottle around 13 to 20 applications
- pH tolerance published as 2-11, so you can check your wheel cleaner against it
- Three spray heads and a microfiber included
Who it is not for
- 12 months is a third of what Mohs EVO claims for a similar amount of prep work
- No SiO2 percentage published
- No US list price published by Gyeon, so cost per application cannot be derived from their figures
