Ceramic Coatings and Protection
Graphene Coating vs Ceramic Coating
It is sold as a new category. It is an additive in an existing one, and the published figures on either side do not show the gap the marketing implies.

What the graphene actually is
Graphene oxide is added to the silica resin. The silica still does what silica does: bonds to the clear coat, resists chemicals, sheds water. Every graphene maker claims advantages around water spotting and heat. None of them publishes comparative data - no test of the same coating with and without the additive - so those advantages are claims about a mechanism rather than measured differences.
The durability gap is a claims gap
The graphene side claims more on paper, and the spread is wide. 3D’s graphene coating claims up to three years, which is the same territory as the two conventional coatings here. Adam’s Advanced claims nine or more, which no conventional coating on this site approaches - and which nobody can verify inside a timeframe that would help a buyer.
Take the most restrained graphene claim and the most restrained ceramic claim and they land in the same place. The additive is not what separates them.
The one real measurement on each side
Adam’s publish a contact angle of 110 to 118 degrees for the Advanced coating, which is an instrument measurement of how hydrophobic the cured film is. CarPro publish 70% SiO2 at 99.9% purity, which is a statement of what is in the bottle. Both are real numbers. They measure different properties, and neither one tells you which coating lasts longer.
How to choose
- You want the modest, checkable claim: 3D graphene at up to 3 years, or CQUARTZ at 2 to 5.
- You want a measured property rather than a claimed one: Adam's Advanced publishes a contact angle.
- You want to size the bottle to your car: Gyeon publish consumption per car.
- You want to know what is in the bottle: CarPro publish SiO2 content and purity.
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.

2The only coating here that publishes its SiO2 percentage
CarPro CQUARTZ UK 3.0
CarPro
CarPro publishes 70% SiO2 at 99.9% purity, a 2 to 5 year durability range, a 10ml-per-coat consumption figure and a 40F to 90F application window. That is four hard numbers on one page, and it is four more than most of this category manages. Buy it because it is checkable, not because 70% is magic.
- Sizes
- 10ml / 30ml / 50ml / 100ml
- SiO2 content
- 70% SiO2, 99.9% purity
- Claimed durability
- 2 to 5 years
- Published consumption
- 10ml per coat
- Application temperature
- 40F to 90F
- In the box
- 30ml bottle, 4 suede applicators, block, leveling towel
- Cure time
- Not published
- Warranty
- Not published
What it does well
- 70% SiO2 at 99.9% purity, published by CarPro on the product page
- Application window published as 40F to 90F, which is the figure that decides whether your garage works in November
- 10ml per coat published, so a 30ml bottle is roughly three coats and the arithmetic is yours to do
- Kit includes suede applicators, a block and a leveling towel rather than just the bottle
Who it is not for
- The durability claim is a three-year-wide range, which is a wide range to plan around
- No cure-time figure published beyond the 2-5 minute buffing window
- Leveling is unforgiving compared with a spray coating; this is not the coating to learn on
How this score was calculated
- Protection claim4.0/10, weight 20%
- CarPro claims 24 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.
- Published SiO2 content8.3/10, weight 22%
- 70%, scored on a band running from 20 to 80. Published by CarPro.
- Cost per ounce4.4/10, weight 16%
- $59.99 for 1.01 oz works out at $59.40 an ounce, scored against a band of $20.00 (good) to $90.00 (expensive) for a ceramic coating.
- Price against the ceiling6.0/10, weight 14%
- A listed $59.99 against the $150 one upgrade in this category realistically tops out at. A list price captured on the compile date, not a live price and not what you will pay.
- Written commitmentdropped
- CarPro 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 transparency7.5/10, weight 18%
- 6 of the 8 specifications we went looking for are published by CarPro. Every blank row below is something the maker will not put in writing, and it costs the product points here.

4The most restrained claim on the page
3D Ceramic Coating+ Graphene Infused
3D Car Care
30ml at $94.99 with a published claim of up to three years — the shortest figure any graphene coating here commits to, and the one most likely to be met. The kit includes a foam block and a suede patch, and 3D states both oleophobic and hydrophobic behavior rather than water beading alone.
- Size
- 30ml
- Claimed durability
- Up to 3 years (ceiling; no minimum published)
- Stated properties
- Hydrophobic and oleophobic
- In the box
- 30ml coating, foam block, suede patch

- Warranty
- Not published
What it does well
- Up to three years is a modest claim in a category that routinely says nine
- Oil repellency stated alongside water repellency, which is a different property
- Applicator block and suede patch included in the 30ml kit
Who it is not for
