TL;DR Handles light connector maintenance · spark plug boots, trailer plugs, battery terminals · but the 104°C temperature limit is below what exhaust-adjacent sensors reach. No SDS located; chemistry is unconfirmed.
Apply a small amount to connector pins and spread a thin coat inside the boot before seating. The 2 oz squeeze tube covers multiple sessions. Well-reviewed by owners, the product earns confirmation of basic moisture and corrosion protection on everyday connections. The key limitation is the 220°F (104°C) upper limit · below the 150°C threshold near exhaust sensors and turbos. With no SDS located, the base chemistry (silicone or petroleum, if silicone-based) is unconfirmed, which affects rubber boot compatibility in high-heat spots.
Good for routine work on a daily driver: spark plug boots, trailer hitch plugs, battery terminals in a mild climate. Skip it near exhaust-adjacent sensors or coil-on-plug boots in a hot bay · the 104°C cap is real. Choose a product with a documented 150°C+ rating for those spots.
No GHS SDS was located; PPE tiers are unconfirmed. The product carries a California Prop 65 listing (confirmed via Amazon and etrailer.com); the specific substance is unknown without SDS §15. Leave-on paste with no drain pathway.
Yes · this product ships as part of Amazon's Add-On program and requires a qualifying order minimum to purchase on its own. Pair it with another auto supply if you only need this item.
The base chemistry is unconfirmed · no SDS was located after an exhaustive search. The 104°C upper temperature limit is lower than typical silicone products (which usually exceed 150°C), suggesting a possible petroleum or petrolatum base. Until an SDS is obtained, treat rubber boot compatibility in high-heat locations as unverified.
