It is a different chemistry from its sibling Mohs EVO, and it carries no manufacturer warranty of any kind. Gyeon positions Pure EVO and Mohs EVO as two different answers to the same question rather than a good-better split: Pure EVO leans toward a deep, wet-looking gloss that Gyeon recommends for show cars and colder, snowier climates, while Mohs EVO leans toward slickness and water-shedding for hot, dusty conditions. Neither one is the premium tier; they are parallel products with different strengths. ## Key facts - Chemistry is **pure SiO2**, described by Gyeon as the highest SiO2 content in its lineup, not the fluoro-polysilazane used in Mohs EVO. - Rated durability: **up to 36 months / 40,000 km on one layer**, extending toward **48 months with a second layer** per retailer application guidance. - No pencil-hardness rating (no published 9H figure) and no coating-thickness figure are published by Gyeon for this product. - Designed as a single-layer coating with a long **10 to 20 minute wipe-off window**, among the more forgiving working times in this category. - No manufacturer warranty program applies to Pure EVO; Gyeon's 10 year warranty program covers Flash and Flash EVO only. - DIY pricing: **$59.95-$59.99 for a 30ml bottle, $84.95-$84.99 for 50ml**, direct from Gyeon-authorized retailers. ## Verdict Gyeon Pure EVO is a legitimate, gloss-focused DIY coating with an unusually forgiving application window, but it is not an upgrade over Mohs EVO, just a different formula aimed at a different priority. Buy it for the gloss and the long wipe-off time, not for any hardness or warranty claim, since neither is published or offered. (Rating: 4.0/5) ## What Makes Pure EVO Different From Mohs EVO Both coatings sit in Gyeon's EVO line and both are DIY-accessible, but they are not tiers of the same chemistry. Pure EVO uses straight silicon dioxide, which Gyeon markets as the highest SiO2 content in its current lineup, built to produce a deep, glass-like gloss. Mohs EVO instead uses a fluoro-modified polysilazane base aimed more at slickness and chemical resistance than peak gloss. Gyeon's own buying guidance splits the two by climate and use case rather than by price or durability: Pure EVO for show cars and colder, wetter regions where gloss matters more and road grit is less constant, Mohs EVO for hot, dusty climates where water-shedding and chemical resistance against baked-on contaminants matter more. Buyers should not assume one is simply the upgraded version of the other. ## Durability: One Layer Versus Two Gyeon's official spec rates Pure EVO at up to 36 months and 40,000 km on a single, standard application. Retailer application guidance extends that to roughly 48 months with a second layer applied about an hour after the first, though sources are not fully consistent on whether a second layer is officially recommended or merely tolerated, so treat the two-layer figure as a retailer-sourced extension rather than a headline Gyeon claim. _Gyeon Pure EVO durability and price_ | Layers | Rated Durability | Bottle Price | Notes | | --- | --- | --- | --- | | 1 layer | Up to 36 months / 40,000 km | $59.95-$59.99 (30ml) | Gyeon's standard, official spec | | 2 layers | Up to ~48 months (retailer guidance) | $84.95-$84.99 (50ml) | Second coat applied about 1 hour after the first | > No pencil-hardness or thickness figure is published for Pure EVO. Judge it on durability months and gloss, not a 9H-style number. ## DIY Application: Why This One Is Beginner-Friendly Pure EVO's main practical advantage over many SiO2 coatings is time. Gyeon's official guidance gives up to 10 minutes before wiping off, and an independent reviewer measured a window closer to 20 minutes depending on temperature and humidity. That is an unusually long margin for a ceramic coating and it directly reduces the risk of high spots and streaking that trip up first-time applicators. Consumption runs roughly 25 to 30 ml per vehicle for a full single-layer application on a sedan, so a 30ml bottle is close to a one-car bottle and a 50ml bottle leaves room for a second layer or a touch-up panel. - pH tolerance of roughly 2 to 11 for washing and chemical exposure - Initial cure is about 12 hours; keep the car out of sun and water during that window - No certified-installer network is tied specifically to Pure EVO, though professional detailers do apply it ## Pricing: DIY Bottle Versus Professional Install Buying direct, a 30ml bottle at about $60 covers one sedan with a single layer, and a 50ml bottle at about $85 covers a sedan with enough left for a second coat on high-wear panels. Gyeon and its retailers do not publish a standard professional-installed price for Pure EVO specifically. Based on where comparable DIY-tier Gyeon and CarPro coatings land when professionally applied, a reasonable installed estimate on a standard sedan is roughly $600 to $1,000, close to the boundary between Coateau's Silver and Gold catalog tiers. SUVs and trucks typically run 20 to 40 percent higher for any coating in this category because of the added surface area. Treat that range as an estimate rather than a published Gyeon figure, and ask any shop quoting Pure EVO for its own written price. ## Should You Buy Pure EVO or Mohs EVO Pick Pure EVO if gloss depth is the priority, the car lives somewhere cold or wet, or it is a show car that spends more time polished than driven daily. Pick Mohs EVO if the car deals with heat, dust and baked-on grime more than it deals with snow, or if the five-minute-plus working window of Mohs EVO's polysilazane base matters more than Pure EVO's longer wipe-off time. Neither carries a manufacturer warranty, so the decision should rest entirely on gloss preference and climate, not on coverage you are not actually getting with either one. ## Frequently asked questions **Q: Is Gyeon Pure EVO the same chemistry as Mohs EVO?** A: No. Pure EVO is a straight SiO2 formula built for maximum gloss, while Mohs EVO uses a fluoro-modified polysilazane base built more for slickness and chemical resistance. They are parallel products, not tiers of one chemistry. **Q: Does Gyeon Pure EVO have a published hardness rating?** A: No. Gyeon does not publish a pencil-hardness figure like 9H for Pure EVO, and no coating-thickness figure is published either. Judge it on the rated durability months instead. **Q: How long does Gyeon Pure EVO actually last?** A: Gyeon's official spec rates it up to 36 months and 40,000 km on one layer. Retailer guidance suggests a second layer can extend that toward roughly 48 months, though that extension is not Gyeon's headline claim. **Q: Does Pure EVO come with a warranty?** A: No. Gyeon's 10 year warranty program covers only its Flash and Flash EVO line through Mobile Certified Detailers. Pure EVO is not named in that warranty's terms and carries no manufacturer coverage. **Q: Can a first-time DIYer apply Pure EVO successfully?** A: Yes, more easily than many ceramic coatings. Its wipe-off window runs up to 10 minutes by Gyeon's own guidance and closer to 20 minutes per independent testing, giving more margin for error than tighter-window coatings. ## Sources - [Gyeon Q2 Pure EVO official product page](https://gyeon.co/product/pure-evo/) - [Gyeon USA: Mohs EVO vs Pure EVO buying guidance](https://gyeonusa.com/blogs/gyeon-products/mohs-evo-pure-evo-which-coating-is-right-for-you) - [Gyeon Q Pure EVO product page and specs (Gyeon USA)](https://gyeonusa.com/products/q-pure-evo) - [Gyeon 10 year warranty program terms (Flash / Flash EVO only)](https://gyeon360.co/upload/files/10_years_warranty_terms_and_condition.pdf) - [Esoteric Car Care: Gyeon Q2 Pure EVO product and layering guidance](https://esotericcarcare.com/products/gyeon-q2-pure-evo)
