From the manufacturer’s Safety Data Sheet, Section 8
“No H319 or H318 in SDS §2 — product is classified non-hazardous. Label reads 'May Cause Eye and Skin Irritation' (precautionary language, not a GHS-level classification). Splash risk during paste transfer or application near face is the relevant trigger.”

From the manufacturer’s Safety Data Sheet, Section 8
“No inhalation H-codes in SDS §2. Silicone paste is non-volatile — no vapor, no respirable mist under normal application conditions. The enclosed-space trigger applies to the generic scenario, not because the chemistry identifies an inhalation hazard.”

CarCareTruth's Analysis
Last reviewed May 17, 2026
TL;DR Proven multi-season protection for spark plug boots, trailer connectors, and battery terminals — nearly 29,000 ratings at 4.8 stars back it up. Standard tube; use a light touch to avoid over-filling connector pins.
What it is and how it performs
Dab on connector pins and coat the inside of spark plug boots before seating. The paste seals out moisture and prevents pin oxidation; salt-belt buyers who pull trailer connectors each spring report clean separation years later. Stable to 150°C for most underhood locations. Packaging downside: no syringe precision; the tip gums up between uses.
Who should buy this — and who should skip it
Best for spark plug service, seasonal trailer connector prep, and battery terminal protection in wet or salt-belt climates. Skip it if you need a single-use dab — a 3 g packet covers a one-time job without leftover.
Safety and environmental impact
The SDS classifies this product as non-hazardous: no GHS hazard codes, no signal word. No inhalation hazard is classified — silicone paste produces no vapor at application temperatures. Eyes and skin precautions on the label are not backed by a §2 GHS classification (no H315, no H319). The paste stays on connectors with no drain pathway; the silicone polymer is not readily biodegradable but carries no aquatic toxicity classification.
