⚔️ Head-to-head
The two coatings enthusiasts actually cross-shop, compared on what's verifiable — brand-claimed durability, kit contents, chemistry, price — and on the application-day differences the spec sheets can't show you.
Both are current, flagship-tier consumer coatings, and neither is a wrong answer — this is a rivalry between excellent products. Gyeon Mohs EVO takes our overall crown on outright performance: its polysilazane chemistry, claimed 36-to-48-month durability, and gloss depth edge out the CarPro. CQuartz UK 3.0 counters where afternoons are won: it's more forgiving to apply, works in wider temperature windows, includes a more generous 50 ml kit for less money than you'd expect, and carries years of documented real-world results. First coating? CQuartz. Chasing the ceiling with steady hands? Mohs EVO.

We verified the obvious staleness risk first: both products remain current flagships. CarPro's CQuartz SiC sits above UK 3.0 as a premium sibling — it replaced the old CQuartz Classic line, not UK — while Gyeon has shipped no successor to Mohs EVO. When enthusiasts cross-shop their first serious coating in 2026, these are still the two names on the shortlist, at street prices within twenty dollars of each other.
They also represent two philosophies. CarPro optimizes for the person applying: tolerance, feedback, documentation-by-community. Gyeon optimizes for the result: chemistry, gloss, longevity numbers with mileage figures attached — a spec-sheet confidence backed by some of the best official instructions in the industry.
On paper Gyeon is more precise and more ambitious: up to 36 months or 40,000 km from one layer, 48 months or 50,000 km from two. CarPro's official claim — '2 to 5 years' — is broader, and it's worth knowing that experienced reviewers commonly report around two years of strong performance as the realistic UK 3.0 outcome. Both claims assume proper prep, curing, and pH-neutral maintenance washing.
Our honest read: on identical, well-prepped cars, expect Mohs EVO to hold its behavior somewhat longer and both to reward maintenance far more than brand choice. The durability gap is real but smaller than the marketing distance suggests.
This is the decision point for most buyers. CQuartz UK 3.0 was formulated for real-world garages: it flashes visibly so you know exactly when to level, tolerates cooler and warmer conditions than most rivals, and forgives a slightly late towel. Four included suede applicators and a leveling towel mean the box covers the job.
Mohs EVO rewards a practiced rhythm — its window is workable but stricter, and the sparser kit (one applicator, no towel) assumes you own supplies. Neither is difficult for a careful first-timer who watches the official videos; one simply leaves more room for a first-timer's pace.
Buy CQuartz UK 3.0 if this is your first coating, your garage conditions are imperfect, or maximum documented value matters: it delivers ninety-plus percent of the flagship experience with the friendliest application in the class and the most coating in the box.
Buy Mohs EVO if you've coated before (or you're a meticulous first-timer with full prep planned) and you want the higher ceiling — the deeper gloss and the longer claimed protection window. It's our #1 overall coating for a reason; it just asks a little more of the person holding the applicator.
CQuartz UK 3.0, in most cases. Its visible flashing, temperature tolerance, and forgiving leveling window are exactly the margins a first application benefits from — and the kit's four applicators and towel cover the supplies. A meticulous first-timer with good conditions can absolutely succeed with Mohs EVO; there's just less room for pace.
Its claims are higher and more precise — up to 36 months per layer, 48 with two, with mileage figures attached — and our overall ranking gives it the durability edge. Real-world, both track prep and maintenance more than branding; expect a modest Gyeon advantage on identical cars, not a different league.
SiC is CarPro's premium sibling (it replaced the old Classic line, not UK 3.0) at a higher price. It's excellent, but it changes the comparison: harder application character and cost closer to pro territory. For the consumer-flagship decision this page covers, UK 3.0 remains CarPro's contender.
Yes — both support a second layer, and Gyeon formally scales its claim to 48 months/50,000 km with two coats. Follow each brand's inter-coat timing exactly. For most daily drivers, one well-applied layer plus seasonal topper maintenance is the sweet spot of effort versus benefit.
The same honest sequence: wash, iron decontamination, clay, polish to your acceptable finish, then a dedicated panel-wipe (CarPro Eraser or Gyeon Prep). Neither kit includes prep chemicals — budget for them, because prep quality decides more of the outcome than the brand choice does.
pH-neutral washing (CarPro Reset or Gyeon Bathe are the matched soaps), no automatic brush tunnels, and a compatible silica topper once or twice a season — Reload 2.0 or WetCoat respectively. Matched-ecosystem maintenance is genuinely convenient, but the products cross-compatibly serve either coating fine.
