From the manufacturer’s Safety Data Sheet, Section 8
“No H314, H315, or H317 classified at the mixture level in SDS §2. SDS §8 specifies nitrile or FKM gloves for general protective use. Skin contact from suede applicator pad is the realistic exposure route — glove use is SDS-recommended during application given the petroleum-naphtha and aromatic solvent carrier.”

From the manufacturer’s Safety Data Sheet, Section 8
“H373 (STOT RE 2 — may cause organ damage through prolonged or repeated exposure) reflects the chronic occupational concern for the petroleum-naphtha/aromatic carrier, not an acute single-session inhalation hazard. No H334 (respiratory sensitizer) or H335 (respiratory irritant) classified in SDS §2. SDS §8 states breathing protection is not required under correct use and normal conditions; specifies respirator only when exposure limits are exceeded or ventilation is insufficient.”

CarCareTruth's Analysis
Last reviewed May 15, 2026
TL;DR Forum members tracking daily drivers report 2–4 years of effective water-beading, strong gloss depth, and contamination resistance. The 5-year label claim is best-case. Temperature-sensitive flash timing trips up first-timers in warm conditions.
What it is and how it performs
Cquartz UK 3.0 bonds a silica-quartz film to paint, glass, metal, and plastic, creating a hard barrier that sheds water and resists iron fallout for years. Apply section by section after decontamination and an IPA wipe. Flash timing is the critical variable: 1–3 minutes at 70–80°F, under 60 seconds above 90°F. The included Reload 2.0 is CarPro's native maintenance booster. Community data puts the typical daily-driver result at 2–3 years; the manufacturer's 5-year claim is a best-case few reviewers confirm.
Who should buy this — and who should skip it
Best for experienced detailers working panel by panel in a temperature-controlled space. Without climate control, first-timers in summer heat regularly produce high spots requiring compounding to correct. A consumer SiO₂ spray kit with a forgiving cure window covers most of the protection at far lower correction risk.
Safety and environmental impact
The SDS (CarPro Global, Rev 5.0, 2025-03-24) classifies this product as DANGER, driven by H304 (aspiration toxicity from the naphtha carrier). The SDS precautionary statement for H304: do not induce vomiting — contact a poison center immediately. H373 (STOT RE 2) is a chronic occupational concern, not a single-session hazard. Flash point 32°C — the SDS precautionary statement for H226 specifies adequate ventilation away from ignition sources. Toluene (~1.5–4%) is a California Prop 65 developmental toxin. The SDS §12 H412 classification means product drips should not enter storm drains.
: AutoGeek Online, thread 128169 — "the UK is still performing" at 15 months; 2–4 year consensus across AutoGeek and Detailing World long-term threads (2022–2025).
Frequently asked questions
How long does CarPro Cquartz UK 3.0 actually last on a daily driver?▾
Community long-term data from AutoGeek Online and AutoDetailing forums (2022–2025) puts typical durability at 2–4 years on a daily driver with routine maintenance washes. CarPro claims 2–5 years, with 5 years described as achievable under ideal conditions. Outdoor daily-driver use with weekly washes typically sees 2–3 years of active hydrophobicity before retreatment is warranted.
What is the flash window for Cquartz UK 3.0 and how difficult is the application?▾
Flash time is highly temperature-dependent: at 70–80°F (21–27°C), most applicators report 1–3 minutes; in heat above 90°F, flash can begin in under 60 seconds; in cool conditions below 60°F, it can stretch beyond 10–15 minutes. AutoGeek forum threads document high-spot formation from under-leveled applications at high temperatures. The product is rated intermediate in difficulty — experienced home detailers succeed, but first-timers in summer heat regularly need correction. Working in a shaded, temperature-controlled garage and tackling one panel at a time is the community-documented approach.
What does '70% SiO2 with 99.9% purity' mean on the label?▾
This refers to the purity of the SiO₂ component itself, not the total SiO₂ content of the working fluid. The SDS §3 does not list a specific SiO₂ percentage. The actual SiO₂ active concentration in the coating formula is not publicly disclosed by CarPro. The label claim describes the quality specification of the silica component used — not the percentage of silica in the bottle. That distinction matters when comparing coating percentages across brands.
Is the Reload 2.0 included in the kit essential, or can I use a different SiO2 booster?▾
The 30ml and 50ml kit versions include Reload 2.0, which CarPro designs as the native maintenance booster for the CQuartz ecosystem. Community evidence on AutoGeek and AutoDetailing forums confirms clean application of Reload 2.0 on CQuartz-coated surfaces without bonding issues. Other SiO₂ boosters can be used for maintenance, but CarPro's own CQuartz maintenance products are the best-documented pairing. CarPro recommends waiting at least 7 days after coating cure before applying any maintenance product.
Why does the SDS show DANGER if this is a consumer ceramic coating?▾
The DANGER signal word in the SDS §2 is driven by H304 (Asp. Tox. 1 — aspiration toxicity). The SDS precautionary statement for H304 specifies: do not induce vomiting — contact a poison center or doctor immediately. H304 means that if the liquid is accidentally ingested and reaches the airways (not swallowed normally), it can cause serious lung damage — a property of petroleum-based liquids in general. This is the same classification applied to Stoddard solvent and naphtha-based products broadly. It is an ingestion-pathway hazard, not an inhalation hazard during normal application. Keep out of reach of children. Applied correctly on an exterior vehicle surface by an adult, the practical exposure risk during application is the aromatic solvent vapors, which the SDS addresses under H373.
