Where CQUARTZ wins
On checkability, comprehensively. CarPro tells you what is in the bottle, how much of it a coat uses, and the temperature range in which it will behave. Those three numbers let you answer the questions people actually have before buying a coating: is this the same chemistry as the cheaper one, how many cars will it do, and can I apply it in my garage in November.
The consumption figure in particular does real work. Ten milliliters per coat means the 30ml bottle is three coats, which is one car with a spare or a small car twice. That is a purchase you can plan. Adam’s 60ml bottle might do four cars or one; the product page does not say, and the accompanying claim of seven-plus years makes the omission more conspicuous rather than less.
The price comparison is closer than it looks
$59.99 for 30ml against $119.99 for 60ml is the same price per milliliter. The Adam’s kit includes surface prep and a booster that CarPro does not, and the CarPro kit includes more applicators and a proper suede leveling towel. Neither is obviously better value; they are the same money packaged differently.
Where Adam's wins
Three genuine things. The kit is more complete: 4oz of Surface Prep in the box means the panel wipe step, which is the one people skip and the one that causes early failures, is not a separate purchase. The Graphene Boost extends the coating without a second trip to the store. And the optional UV flashlight makes high spots visible while they are still fixable, which on dark paint is worth more than most specifications on this page.
There is also the plain matter of the claim. Seven-plus years is an enormous number and it is not impossible; the honest position is that neither we nor any reader can verify it inside the timeframe it describes, and Adam’s has not published data supporting it. Treat it as a marketing position rather than a specification, and buy the product for the kit rather than for the number.
Who should buy which
- First coating, dark paint, want as much help as possible: Adam's, for the surface prep in the box and the UV tracing option.
- Have coated before, want to know what you are buying: CarPro, for the published silica figure and consumption rate.
- Coating a car in a cold garage: CarPro, because it is the only one of the two that publishes an application temperature window.
- Coating more than one vehicle: CarPro, because you can work out how far a bottle goes before you buy it.
- Want the biggest number on the label: Adam's, with the caveat above.
What neither one tells you
Neither publishes a coverage figure in square feet. Neither publishes an independent test result. Neither publishes what happens at year three, which is the year that decides whether either claim was worth paying for. That is not unique to these two — it is the state of the whole category, documented across the main coating roundup.
What decides your result more than either bottle is the preparation underneath it. Both coatings bond to bare, decontaminated, oil-free clear coat and to nothing else. If you have not done chemical decontamination and a panel wipe, the difference between these two products is irrelevant, because neither will reach its claim.
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 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.

2The biggest claim on the page, and the fullest kit
Adam's Graphene Ceramic Coating
Adam's Polishes
Skip this one. A 7+ year claim on a DIY coating is the kind of number that is impossible to falsify inside the warranty period and impossible to verify outside it. If the claim is what is selling you, buy the coating that publishes a coverage figure instead.
Adam's publishes 7+ years of protection and >10H hardness on a 60ml bottle at $119.99, in a kit that includes surface prep, a booster, applicators, towels and gloves. The claim is the largest in this ledger by a factor of two, and Adam's publishes no coverage figure to go with it, so you cannot work out how many cars the bottle does.
- Size
- 60ml
- Claimed durability
- 7+ years
- Claimed hardness
- Greater than 10H

- 60ml coating, 4oz Graphene Boost, 4oz Surface Prep, 4 towels, 2 applicators, gloves

What it does well
- 7+ years claimed, the longest figure any maker in this ledger publishes
- Kit is genuinely complete: 4oz Surface Prep, 4oz Graphene Boost, applicators, suede and soft towels, gloves
- 24-hour cure window published plainly on the page
- A UV tracing feature is offered so you can see where you have already coated
Who it is not for
- No coverage or consumption figure published, so cost per car is not calculable from Adam's own numbers
- No SiO2 or graphene percentage published; >10H hardness is a claim, not a number you can check
- $119.99 is the highest list price here and the bottle is 60ml
How this score was calculated
- Protection claim10.0/10, weight 20%
- Adam's Polishes claims 84 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
- Adam's Polishes 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 ounce4.4/10, weight 16%
- $119.99 for 2.03 oz works out at $59.11 an ounce, scored against a band of $20.00 (good) to $90.00 (expensive) for a ceramic coating.
- Price against the ceiling2.0/10, weight 14%
- A listed $119.99 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.
