HydroSilex Recharge Ceramic Coating

The label claims up to 1 year, but community data from long-term owner reviews and r/AutoDetailing threads consistently puts real-world durability at 3-4 months on a regularly-washed daily driver. That is roughly three times shorter than the label maximum. The coating works, and the water-beading after application is real and noticeable, but it fades meaningfully after about a season on a car that sees regular washing.

Nothing is mandatory. The SDS classifies the mixture as not meeting the criteria for classification; no signal word, no GHS pictograms, no health hazard codes at the mixture level, and the formula is water-based with a trace glycol ether co-solvent under 0.5% by weight. That said, SDS §8 does name eye/face protection, gloves, and respiratory protection for poor ventilation, so all three appear on this page as situational precautions with the conditions attached: eye protection when spraying at face height or decanting from the gallon jug, gloves for repeated all-day handling or sensitive skin, and ventilation or a respirator if you are spraying inside a closed garage. Outdoors, on a car, for one pass, gloves are the only one most owners bother with.

No. SDS §3 lists no fluorinated ingredients. The active, aminodimethylsiloxane, is a nitrogen-functional silicone polymer, not a fluorinated compound. The co-solvents (butoxypropanol and diethylene glycol monobutyl ether) are also non-fluorinated. The PFAS-free conclusion is based on affirmative SDS §3 disclosure, not an absence of evidence.

The manufacturer recommends a fresh wash before application, and ideally clay-bar decontamination or an IPA panel wipe for longer-lasting results. These prep steps are not listed as mandatory in the TDS, but community feedback consistently shows better hold time on properly decontaminated paint. A clay bar and panel wipe are not included with the bottle; they are available separately and are not required for first-time use.
