Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 aspiration toxicity — thin, oily liquids can slip into the lungs if swallowed, causing chemical pneumonia.
If swallowed, inhaled, or splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.
About this product's hazards. This product's Safety Data Sheet uses signal word danger. Read the manufacturer's SDS and follow all safety instructions before use.

TL;DR Community-confirmed 2·3 years of protection on daily drivers · the "up to 5 years" label is a best-case ceiling, not a median. Immediate wipe-off format is beginner-friendly; a separate IPA degreaser for panel prep is required but not included. DANGER signal word from the petroleum distillate carrier's aspiration hazard.
Crystal Serum Light is Gtechniq's consumer-accessible coating · the DIY tier between the installer-only Ultra and maintenance-spray EXO. It bonds to clear coat, sheds water, and resists iron contamination for years. Wipe each panel with IPA or a panel degreaser (sold separately), apply with the included suede applicator, wipe off immediately · no timed flash window. Vehicle stays indoors for 12 hours. owners confirm 2·3 years of effective protection on regularly washed daily drivers exposed to direct summer sun. The "up to 5 years" label is a best-case ceiling; community data puts the typical outcome closer to 3 years.
Best for home detailers who want professional-brand durability in a forgiving wipe-off format and are comfortable sourcing an IPA degreaser separately. Skip it if you need a fully self-contained kit or want maximum single-coat longevity · polysilazane coatings with 4-year community data exist at similar price points, though they carry steeper application requirements.
DANGER signal word: H227 (combustible liquid · fire hazard, not a health hazard) and H304 (aspiration hazard, ingestion pathway only). The SDS precautionary statement for H304 specifies: do not induce vomiting · contact a poison center or doctor immediately. Third-party retailers display a California Prop 65 warning; SDS §15 does not identify the specific substance, but kerosene-class petroleum distillates can contain Prop 65-listed substances. No skin, eye, or respiratory H-codes at mixture level in SDS §2. Apply outdoors or with garage door open per SDS ventilation guidance. No PFAS per SDS §3. Cured film stays on the vehicle surface. SDS revision date is 2020-07-01 · verify against current manufacturer SDS before re-scoring.
owners tracking the coating on daily drivers report 2·3 years of effective protection. The label claims 'up to 5 years' · that represents a best-case ceiling on an ideally maintained vehicle, not a typical daily-driver outcome. Community long-term data consistently lands in the 2·4 year range.
SDS §3 lists no fluorinated ingredients. The active coating chemistry is proprietary, but no per- or polyfluoroalkyl substances were identified in the disclosed formula.
Yes · the immediate wipe-off format eliminates the high-stakes flash window timing that trips up first-timers with other ceramic coatings. You apply to a panel and wipe off right away, then buff with a second microfiber. A separate IPA wipe or panel degreaser is required for proper surface prep · this is not included in the kit.
The SDS signal word is DANGER, driven by two codes: H227 (combustible liquid, a physical fire hazard from the petroleum distillate carrier) and H304 (aspiration hazard · ingestion/aspiration pathway, not a vapor inhalation hazard). The SDS precautionary statement for H304 specifies: do not induce vomiting · contact a poison center or doctor immediately. Applied outdoors, the combustible and aspiration hazards are not relevant to normal application.
Third-party retailer listings (including Autogeek.net) display a California Prop 65 warning. The SDS §15 does not identify a specific Prop 65-listed substance. Kerosene-class petroleum distillates can contain trace Prop 65-listed substances, but the specific triggering ingredient is not confirmed. The Prop 65 warning applies · the specific substance remains unverified in SDS §3.
