Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.

other is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
The full breakdown
What it's made of and why it matters
303 Marine Aerospace Protectant is a silicone or acrylic-based UV protective coating formulated to restore shine and resist UV degradation on marine vinyl, rubber, and plastic surfaces. The product contains volatile organic compounds (VOCs) as solvents to enable application; exact resin chemistry is proprietary and not disclosed on the label or safety data sheets available to consumers. Silicone-based coatings of this type typically do not off-gas formaldehyde or release phthalates, but solvent volatility during and after application poses inhalation risk in enclosed spaces.
The brand's record and disclosure
303 Products is a well-established marine and automotive care brand owned by the Armor All/SC Johnson portfolio; the company has not publicly disclosed PFAS presence or absence in this formulation, nor are there published third-party test results for PFAS content. The brand provides basic SDS (Safety Data Sheet) information but does not offer independent certifications like Cradle to Cradle or GreenGuard for this marine protectant line. No major recalls or contamination incidents are on record for this specific product.
How it compares in its category
Marine and automotive protectants in this category (silicone or acrylic-based aerosol or liquid coatings) are largely unregulated for PFAS, and 303 is typical in offering no independent PFAS testing. Some competitors such as Star brite and Meguiar's likewise do not disclose PFAS, while others do not publish ingredient detail at all. Water-based or solvent-free UV protectants exist (e.g., some plant-oil-based products) but are less common and offer shorter durability; 303's silicone formulation is mid-range for performance and hazard transparency.
If you buy it
Apply in well-ventilated outdoor or ventilated indoor spaces to minimize inhalation of VOCs; avoid spraying directly on skin or into eyes and wash hands after use. Do not apply to areas where runoff will enter water systems, especially in marine settings, as the protective coating can persist in sediment. Reapply every 3 to 6 months depending on UV exposure and surface weathering; replace once the protective layer visibly degrades or loses water-beading properties. Store in a cool, dry place away from heat and ignition sources, as the product is flammable.
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) inhalation risk
Solvent carriers in this protectant (typical to silicone coating formulations) evaporate during and shortly after application; inhalation in poorly ventilated spaces poses respiratory irritation and CNS effects at high exposure.
Eye and skin irritation from direct contact
SDS indicates the product causes eye irritation and may cause skin irritation or sensitization in some users; buffering with water and seeking prompt rinsing is standard first aid.
PFAS presence (undisclosed composition)
Proprietary formulation and silent brand stance on PFAS disclosure mean presence cannot be ruled out; some silicone-based coatings and water-repellent finishes contain PFAS for durability, though not confirmed for this specific product.
Environmental persistence and aquatic accumulation
Protective silicone coatings are designed to resist degradation and persist on surfaces; runoff into water systems poses potential bioaccumulation risk, particularly in marine environments where the product is intended for use.
Flammability hazard during storage and use
Product contains flammable solvents and may be packaged as an aerosol or liquid concentrate; improper storage near heat or open flame, or use near ignition sources, poses fire risk.
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.
