CarCareTruth's Analysis
Last reviewed May 19, 2026
TL;DR Non-PFAS coating in a solvent-base carrier — the brand cites an AATCC ISO 5 lab repellency mark, but community durability data on the v2 reformulation is thin. DANGER signal word is driven by H225 (highly flammable solvent, 12 °C flash point) — a physical hazard, not a health-tier code. The antimicrobial AB variant is not the brand's recommended choice for convertible soft tops; the non-AB I1 is the soft-top version.
What it is and how it performs
I1AB is applied as a pump spray onto clean, dry fabric — the 1 L size ships as a refill bottle, so decanting into a trigger sprayer is the documented application method. The 29-rating Amazon US corpus is bimodal on bead-test outcome: one reviewer reports water beading then penetrating mats, another reports beading restored after reapplication. Fabric darkens during application and returns to original color when dry. Oversaturation can leave white marks.
Who should buy this — and who should skip it
A reasonable pick for buyers who want a non-fluorinated coating with the added Biocote antimicrobial. Skip it if a convertible soft top is the target — the brand directs soft-top users to the non-AB I1. Buyers who want a more community-validated non-PFAS option will find a longer track record on 303 Fabric Guard.
Safety and environmental impact
These are the GHS classifications from the SDS. The PPE tiers below are translated from these codes and the underlying ingredient chemistry — not from generic SDS Section 8 boilerplate.
DANGER is driven by H225 (highly flammable liquid, 12 °C flash point) — a physical hazard from the propan-2-ol carrier, not a health-tier code. The health-relevant codes are H317 (skin sensitizer), H319 (eye irritant), and H336 (drowsiness/dizziness via the CNS route); H336 with the pump-spray modifier is the dominant health-axis driver and the basis for the lungs recommended tier. SDS Section 3 confirms a non-fluorinated formula. The environment score reflects H402 (Aquatic Acute Cat 3) plus the solvent-carrier VOC load and the leave-on pathway.
Frequently asked questions
Is Gtechniq I1AB Smart Fabric PFAS-free?▾
Yes — the Safety Data Sheet (v1.0, 07/01/2020) discloses propan-2-ol at ≥60% and zirconium tetrabutanolate at 1–20% as the two named ingredients in Section 3. No fluoropolymer, fluorotelomer, or any fluorinated compound appears anywhere in the ingredient disclosure or the §16 H-statement list. The Amazon listing also states the formula is 'flurocarbon free.' The hydrophobic active is a zirconium-ester coating chemistry — non-fluorinated.
Can I use I1AB Smart Fabric on a convertible soft top?▾
Per the Amazon listing description: 'the Non AB version of I1 Smart Fabric should be used on convertible roof.' The brand publishes both an AB (antimicrobial) version — this product, ASIN B014HIXO30 — and a separate non-AB version. The AB variant is not the brand's recommended choice for convertible soft tops; look at the non-AB I1 if a soft top is the target surface.
What does the AB in I1AB mean?▾
AB stands for Anti-Bacterial. The AB variant adds Biocote silver-ion antimicrobial technology to the I1 chemistry. The antimicrobial active is below the 0.1% Safety Data Sheet mixture-disclosure threshold and is not enumerated in §3. The chemistry difference between the AB and non-AB versions also adds H402 (Aquatic Acute Cat 3) to the AB variant's hazard classification.
Why does the bottle say DANGER if the chemistry isn't fluorinated?▾
The DANGER signal word is driven by H225 — the propan-2-ol carrier solvent is a highly flammable liquid with a 12 °C flash point. That is a physical hazard (fire/ignition), not a health classification. None of the SDS Section 2 codes that would normally drive a health-tier DANGER deduction (H304, H314, H318, H330–H334, H340, H350, H360, H370, H372) are present on this product. The health-relevant codes that are present — H317 (skin sensitizer), H319 (eye irritant), and H336 (drowsiness/dizziness via CNS) — are scored separately and account for the health-axis deductions.
How is the 1 L bottle applied?▾
The 1 L size ships as a screw-cap refill bottle, not pre-fitted with a sprayer. Gtechniq's documented application method is to decant into a trigger sprayer and spray a thin, even coat onto clean, dry fabric. The 12 °C flash point of the carrier solvent means application should be away from any ignition source, and the vehicle cabin is an enclosed space — apply with doors open.
How long does I1AB protection last?▾
Community evidence is thin — the Amazon US listing carries 29 ratings at 4.4 stars, and most detailing-forum coverage of the broader I1 family discusses the older fluoropolymer-based v1 formula. The v2 reformulation away from fluoropolymer chemistry is recent enough that long-term durability follow-ups are sparse. Plan for reapplication on the conservative end of the category window until more time-stamped community data accumulates.
