What 303 Products Automotive Protectant is made of, ingredients and materials
303 Automotive Protectant is a polymer-based UV coating designed to protect vinyl, rubber, plastic, and leather surfaces from solar degradation. The formulation contains aliphatic hydrocarbons, silicone polymers, and UV absorbers that form a thin protective film. The exact polymer type (silicone elastomer vs. acrylic vs. polyurethane backbone) is not disclosed by the brand, which limits precise hazard assessment for degradation byproducts or off-gassing potential.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Volatile organic compounds (VOCs) and solvent off-gassing
Polymer-based coatings typically contain aliphatic hydrocarbons as carriers. 303 does not publish VOC content or low-VOC certification; indoor or closed-space application could expose users to respiratory irritants, particularly with poor ventilation.
Skin and eye irritation from undisclosed surfactants or additives
Formulations of this type often include emulsifiers and wetting agents not listed on consumer-facing labels. Direct contact risk is low during normal application, but splash exposure could cause irritation; no safety data sheet appears publicly available.
Polymer coating degradation and microparticle shedding
Over time, UV-exposed polymer coatings can fragment and shed microparticles onto surfaces touched by hands or inhaled during application of subsequent coats. The polymer base type is undisclosed, so durability and degradation risk cannot be assessed precisely.
Accidental ingestion risk from residue on high-touch surfaces
If applied to areas children or pets contact frequently (dashboard, steering wheel), incomplete curing or reapplication could leave residue transferable to mouth. The product is not food-safe and overdose of aliphatic hydrocarbons or polymers could cause gastrointestinal distress.
What’s reassuring
Heavy metals
Modern UV absorbers are typically organic (benzotriazole, hindered amine light stabilizers) rather than heavy-metal salts, and no recalls or warnings for 303 exist on record. However, the brand does not disclose additive sources, leaving this unverified.

The brand's record and disclosure
303 Products maintains minimal public transparency on ingredient composition or manufacturing certifications. No PFAS testing data, VOC certifications, or third-party safety audits appear in publicly available materials. The brand has no documented recalls or known safety controversies in the automotive protectant space, but silence on composition is a structural transparency gap rather than evidence of safety.
How it compares in its category
Automotive UV protectants span a wide spectrum, some brands disclose silicone-only formulations, others use wax blends, and a few publish VOC and chemical inventories. 303's market position as a premium product does not correlate with disclosed safety data; comparable alternatives from brands with ingredient transparency or low-VOC certifications offer equivalent protection with clearer hazard profiles.
If you buy it
Apply in well-ventilated areas to minimize inhalation of solvent vapors. Avoid contact with eyes and skin; wash hands after use. Reapply every 3-6 months depending on UV exposure and weather. Store in a cool, dry place away from heat sources and direct sunlight. Do not apply to steering wheel or brake pedal surfaces where grip is safety-critical.
