303 Aerospace Protectant
Aerospace protectant; water repellent chemistry raises concern. Check ingredient list.
303 Aerospace Protectant is a silicone-based UV and water protectant for vehicles and outdoor materials. Brand provides no PFAS disclosure; water-repellent formulations sometimes contain fluorinated compounds, but full ingredient transparency lacking.

The full breakdown
What it's made of and why it matters
303 Aerospace Protectant is a silicone-based coating designed to protect vinyl, rubber, plastic, and leather from UV damage and water. The water-repellent function typically relies on hydrophobic chemistry that may include fluorinated compounds (PFAS-class) or siloxane polymers. The UV inhibitor package and slip agents are standard in automotive protectants but are not itemized on the label, which limits transparency about specific chemical exposure.
The brand's record and disclosure
303 Products (owned by SC Johnson) does not publicly disclose PFAS content or commit to PFAS-free formulation on product labels or their website. The brand has not achieved third-party certifications (e.g., Cradle to Cradle, EPA Safer Choice) for this product line. No major recalls or safety controversies are on public record for 303 Aerospace Protectant itself, but the parent company's silence on water-repellent chemistry ingredients is notable given widespread PFAS scrutiny in consumer coatings.
How it compares in its category
Silicone-based protectants dominate automotive and furniture care. 303 is mid-market in price and widely used. Alternatives include non-silicone UV-block sprays (e.g., plant-oil based) and wax-only products that avoid water-repellent polymer chemistry entirely. Few competitors in the spray protectant category disclose PFAS status either, making this a category-wide transparency gap rather than a 303-specific failure.
If you buy it
Apply in well-ventilated areas or outdoors to avoid inhaling spray aerosol and volatile silicone carriers. Test on inconspicuous material first (vinyl, plastic) because buildup can leave a slick residue if over-applied. Reapply every 3-6 months depending on sun and moisture exposure. Do not use on steering wheels or grip surfaces where slipperiness poses a safety hazard; avoid contact with skin and eyes.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Volatile organic compounds (VOCs) from spray carrier
Silicone protectants are typically suspended in hydrocarbon or siloxane solvents that off-gas during and after application. No VOC content limits are published by 303; inhalation during application in confined spaces could cause respiratory irritation.
Siloxane polymer bioaccumulation
Cyclic siloxanes (D4, D5, D6) used in some silicone formulations are volatile and persist in aquatic environments. Exact siloxane profile in 303 Aerospace is not disclosed; runoff from treated vehicles or furniture could accumulate in soil and water over time.
Surface slipperiness hazard
User reports and vehicle maintenance guides document that silicone protectants can create slick buildup on steering wheels, pedals, and furniture seams if over-applied, increasing slip and control loss during use.
Lack of ingredient transparency for UV inhibitors and slip agents
303 does not itemize UV blockers or anti-slip modifiers on the label. These additives may include heavy metals (e.g., titanium dioxide, iron oxides) or allergen-class compounds not flagged for sensitive users.
Aerosol inhalation from spray application
Spray format delivers fine particles and volatile components directly to respiratory tract. Prolonged or poorly ventilated use, especially indoors, poses acute irritation risk; chronic exposure data for this specific formulation is not publicly available.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
