From the manufacturer’s Safety Data Sheet, Section 8
“GHS NOT CLASSIFIED — no inhalation H-codes (H330, H331, H332, H334, H335, H336). Formula is 70–99% water with non-volatile linear PDMS as active — no volatile solvents. Pump-spray mist in the confined car cabin (~3 m³) is the only plausible inhalation pathway; the chemistry does not support respiratory concern under normal use.”

CarCareTruth's Analysis
Last reviewed May 15, 2026
TL;DR Delivers a matte, factory-fresh finish that community reviewers consistently describe as non-greasy and natural-looking, with no windshield glare documented — UV protection is label-claimed but relies on the silicone film rather than a disclosed absorber chemistry. GHS not classified in the current 2022 SDS; Prop 65 listed for trace processing byproducts.
What it is and how it performs
A water-based silicone protectant that leaves a matte, factory-fresh appearance on plastic, vinyl, and rubber with no oily residue — the most consistent community observation. Spray onto a microfiber cloth first to avoid pooling in vents and grilles; a second dry-buff levels the finish. Community reports praise durability and dust repulsion, though no week-count follow-up data appears in the review corpus. UV protection comes from a physical silicone film, not a named absorber.
Who should buy this — and who should skip it
Best for owners who want a satin or natural finish rather than high-gloss — particularly in high-UV climates where interior plastics fade. Skip it if surfaces carry heavy silicone-oil buildup — strip first for even adhesion. Buyers wanting a wet-shine look should look elsewhere.
Safety and environmental impact
The 2022 SDS classifies this as GHS not classified — no signal word, no hazard codes. Prop 65 listed for ethylene oxide, a trace manufacturing residual. Leave-on product, not drain-destined. No cyclic siloxanes (D4/D5); linear PDMS is confirmed biodegradable in water by the SDS. Two surfactant components carry aquatic toxicity concerns at the ingredient level.
Frequently asked questions
Does 303 Automotive Protectant leave a greasy or shiny finish?▾
No. Community reviews consistently describe a matte, factory-fresh appearance with no oily residue or slippery feel. This is one of the product's most frequently cited strengths — multiple buyers specifically note it looks natural rather than 'dressed.'
Does it cause windshield glare?▾
No glare complaints appear in the review corpus. The finish dries matte and non-reflective, which distinguishes it from older silicone-oil protectants that can create glare visible in the windshield under direct sun.
Does 303 Automotive Protectant protect against UV?▾
The label claims UV protection. The disclosed chemistry relies on a physical PDMS silicone film barrier — no named UV absorber (such as benzotriazole or HALS compounds) appears in the SDS. Community reports include long-term durability claims, but the mechanism is the film, not dedicated UV-absorbing chemistry.
Should I spray directly on the dashboard?▾
Spray onto a microfiber cloth first, then wipe the surface. Direct spray can pool in vents, speaker grilles, and trim gaps, leaving uneven coverage. A second dry-buff removes any excess and ensures an even matte finish.
Why does it have a Prop 65 warning?▾
The SDS lists ethylene oxide as a Prop 65 substance — it is a trace residual from the manufacturing process of the ethoxylated surfactants in the formula, not an active ingredient. The Prop 65 warning is triggered by any detectable presence, regardless of dose.
How is this different from 303 Aerospace Protectant?▾
These are distinct products from the same brand. The Automotive Protectant (part number 30382CSR) is a 16 oz pump spray formulated specifically for automotive interiors. The Aerospace Protectant (30308CSR/30313CSR) is the original formula used on aerospace surfaces and is available in more size variants. Both share a similar water-based PDMS chemistry and the same SDS document, but they are separate SKUs.
