From the manufacturer’s Safety Data Sheet, Section 8
“H361 (suspected reproductive toxicant Cat 2) from toluene and D4 per SDS §2, plus H315 (skin irritation) from multiple components. H361 chemistry warrants consistent glove use — even intermittent contact with a reproductive toxin is a meaningful exposure concern.”

CarCareTruth's Analysis
Last reviewed May 19, 2026
TL;DR Strong color restoration on faded trim with a factory-satin finish — but multi-month durability is unverified; Gyeon's 24–36 month claim can't be confirmed by community data. H361 (suspected reproductive toxicant) from toluene and D4 in the formula means gloves are warranted per the GHS classification.
What it is and how it performs
Applied by foam applicator to plastic and rubber trim, this 30 mL bottle cures to a ceramic coating that restores color and repels water. Reviewers describe immediately darker, factory-rich trim — "looks like new again" is a repeated description across the 350-review pool. Application is unusually forgiving: one reviewer documented clean results after applying outside the temperature range, in direct sun, with rain two hours later. The included applicator gets minor criticism. Gyeon claims 24–36 months of protection; no independent long-term community data with wash-frequency context exists to confirm or refute that figure.
Who should buy this — and who should skip it
Right for an owner with faded plastic or rubber trim who wants a natural satin look and is comfortable with gloves-required reproductive-toxin chemistry. Skip it if trim is chalking or pitting — restore first, then coat. Skip it also if you need a verified long-term durability story.
Safety and environmental impact
SDS §2 WARNING signal word: H361 (suspected reproductive toxicant Cat 2) from toluene and D4, H335 (respiratory irritation) from the titanate and aromatic co-solvents, H304 (aspiration hazard) from the petroleum fraction. Toluene at 0.5–1.5% is Prop 65-listed. SDS §14 explicitly states no aquatic hazard — aquatic_toxic: false. Not biodegradable; estimated VOC ~106 g/L; not CARB-compliant. No PFAS.
Frequently asked questions
How long does Gyeon Q² Trim EVO actually last on a daily driver?▾
The manufacturer claims 24–36 months. Community long-term durability data with wash-frequency context is not yet available as of 2026-05-18 — this product has no AutoGeek forum threads or verified multi-month Amazon follow-up reviews with explicit wash frequency. The short-term evidence (350 Amazon reviews, predominantly 5-star) shows strong immediate color restoration and retention through initial washes, but the rubric requires independent multi-month data before the durability claim can be scored above provisional. Score conservatively until that evidence exists.
Does Gyeon Q² Trim EVO contain PFAS?▾
No. The SDS §3 lists no fluorinated ingredients. The formula is an aminosiloxane-based ceramic coating — a silicon-oxygen polymer chemistry, not a fluoropolymer. The D4 (octamethylcyclotetrasiloxane) component is a cyclosiloxane, not a PFAS compound.
Why does this product have a Prop 65 warning on CarCareTruth?▾
Toluene (CAS 108-88-3), present at 0.5–1.5% in the formula, is a confirmed Prop 65-listed substance. The Amazon listing does not flag Prop 65, and the Canadian SDS §15 covers Canadian regulations only. The warning is applied precautionary based on ingredient presence — re-verify when a US-format SDS or physical product label is available.
Can this be applied indoors or in a garage?▾
The SDS §8 specifies H335 (respiratory irritation) from the TTIP and xylene components, and the SDS notes H336 (drowsiness/dizziness) from the petroleum solvent carrier. SDS §7 calls for adequate ventilation. Applying in a fully open garage or outdoors is appropriate. An enclosed garage with poor airflow is not recommended per the SDS ventilation specification.

Looks Good
Went in on. Looks good. Waiting to see how long it lasts. In my experience nothing last but this looks promising
